I know enough about taxes to hire an accountant.
The Reddit r/personalfinance sub is a well moderated place (no shady experts shilling nonsense). Take a look at their wiki[1] for a good jumping off point.
There are also country specific pf reddits listed in their wiki if you're not in the US.
The basic jist of things is:
1. Create a budget, go through the last few months of bank statements and categorise your spending
2. Pay down your debt (starting with the highest rate first)
3. Save 3-6 months expenses (which you know from your budget) as an emergency fund. (This does not need to all be accessable immediately just available, say 80% in a savings account with 30 days notice)
4. 2 & 3 should be done at the same time, it might not be mathematically the best but paying all your debt off and then being fired/made redundant without a cushion is not good.
Then once you've got a handle on the pf stuff, think about r/financialindependence or r/fire
