How did you file 2020 this year? Did you print and mail the one you did back in 2021? Or did you do it again in the Online version? Online is only good for 2021 now. Does it say Accepted for 2020 or for 2021?
If you efiled 2020 this year in the Online version it thinks it was your 2021 return. If it was Accepted (now in 2022) you need to amend it and change it to be for your real 2021 return. You will have to start the Amended return with the original return that was filed. How to amend 2021

You have to file each year separately. You didn't enter both 2020 & 2021 into the same online return, did you?
