It seems you're trying too hard and in the wrong places. Stabilizing your budget is easy once you know the basics, even for nations with terrible economies, which Sweden isn't 1 of. It's all about manipulating the different sliders and getting a few key techs to get you out of the red and once there it's easy to stay out of it. As Sweden you have amazing literacy right from the get go, so you don't need to focus culture techs like most other nations. It also means that you can start industrializing right from the start and your factories will actually work properly as you have a high enough literacy for both craftsmen and clerks, unlike say Russia who has to wait a long time for their populous regions to be literate enough to finally industrialize(typically takes 20-30 years just for 2-3 provinces to start with.
No idea what year you're in your current game nor what your current situation is so I'll post some general advice assuming you're starting from scratch(so if you don't want to restart adjust according to your current situation). As Sweden your #1 tech priority on day 1 is Medicine, since your population is low you need it to grow as much as it can as fast as it can and Medicine is the only tech in the game that lets you do that. After that since your literacy is insanely high right from the start you can skip the usual culture techs and instead go for commerce and industry ones. Most notably the first row in the industrial tree(increased mining and farming output which improves your early economy by a lot) and several columns in the commerce tree, including the first 2 columns to increase tax and admin efficiency as well as the business column whose early techs also increase mining and farming output alongside increased diplo points and access to some factories. Leave the factory techs for later.
As far as the sliders go, keep education and admin sliders to 100% until you have too many bureaucrats across your entire nation than drop it to 50%, same with education once you have at least 2% clergymen across your entire nation. Only drop these sliders further and immaturely if your budget is a complete disaster, which should never happen as Sweden. When it comes to your navy, you should just disband it. You won't need it for anything early on and when you'll start wanting to have a navy you'll want better ships anyway. It goes without saying that you should drop the navy slider to its minimum(30%) as even without a navy you will still buy artillery for example which you won't really use. Your army slider should also be minimized(0% if desperate otherwise 10-20% is good enough), only raise it to 100% a few months before declaring war. The military slider(the 1 below the education and administration scales) should generally be kept at its default 50%, feel free to lower it temporarily if your budget is heavily struggling(again shouldn't really happen as Sweden) than bring it back up to 50% when stabilized. Social Spending and the Industrial scales should both be kept at 100%, the social spending won't take effect anyway until you get some social reforms, at which point you'll want to invest money to make them work so just leave it at 100% all the time, the industrial scale should be kept at its default max too as you'll always want to make sure your factories get all the resources they need as they'll quickly become your primary money makers. Lastly, the tax and tariff sliders. At the very beginning you should put them all to 100%, the effective tax will be pitiful so you won't actually get too much from it even maxed. As soon as you can drop tariffs first than start gradually(a few percentages at a time) dropping taxes(first middle than poor than rich, contrary to what most people say) until eventually you'll minimize them at 25%(if you have a State Capitalism party in charge, which you should until the mid-late game at the very least).
