Interested in starting a Teachers Pay Teachers but scared of taxes (Maryland)

I’m interested in starting a Teachers Pay Teachers (TPT) account. I’m a high school teacher that creates organizational resources for teachers that are somewhere between type A and type B. My goal is not to get rich or replace my main source of income, but I think it’d be cool to maybe make a couple dollars from resources I already make and use in my classroom.

However, I have an irrational fear of being hauled off to prison by the IRS (even though I know that it is unlikely that I’ll make much more than $10 a month starting out). Soooo, how do taxes for TPT sellers work? Do I need anything specific to sell on TPT in Maryland? Does TPT collect and report/pay sales tax to the state? Any experience or advice would be appreciated!
