answer was:
"You do not enter a contribution that was *for* 2020 on the 2021 tax return, It must be entered on your 2020 or amended 2020 tax return if not entered on the 2020 return. You must also make sure that it was non-deductible to generate a 2020 8606 form"
my question remains: HOW CAN I COMPLETE TT2021 FILING? amended 2020 8606 (paper submission?) does not automatically referred by TT2021.
