Deductions & credits

I didn't have insurance fo 2020, so i had to pay that year. I had insurance last year so i don't want to pay this year but i might have to because I don't know where to find the information about premiums. I don't understand taxes and benefits and stuff like that and just fill out something on the forms so I usually have to pay taxes in some way...I probably should have a professional do it because I don't really understand most of the questions or answers on this site but it's very expensive where i live.
