I have no idea how to do taxes at all

They never taught us this in school in my country tbh and I live alone. I never had to do it before because my company sorts it out for me (the year end stuff) and we didn’t have this back in my home country

I’m planning on quitting soon and started a freelance thing where people subscribe to me on websites like patreon and that’s how I make money with it. I make more with it than my regular job so I’d like to focus on it.

But since it is freelance, I have no idea how to keep record of my earnings and expenses related to the freelance as I’m told here that that’s what I need to pass next year to know how much taxes I’ll pay. I’m confused since people subscribe, patreon sends the total to PayPal and I use PayPal to send it to my bank. That’s about it. There are no invoices.

I’m ashamed to not know any of these things but I would like some guidance on how to keep track of it all to make it easier when I need to compile everything for next year.

I’m a bit slow and on the spectrum and alone since I recently cut off my family, this is the only place I can ask. Detailed instructions would be very appreciated. Like what would I need from my paypal account or bank. Statements and how to use them. What to bring, etc.

I thought might be a good idea to sort everything when it’s the end of the month but I have no idea how to approach it.
