After you file

If you did NOT use TT for the 2020 return  and you accidentally transferred in the 2020 information into the 2021 program then you need to start again from scratch and this time choose to NOT transfer the 2020 information.   OR  you can continue with the current 2021 return and make any corrections as needed as you continue thru the interview.  Ignore the comparison screens as you know they will not be correct.
