Re e-file 2020 by transferring all filed data to new TTforms

I E-filed my 2020 TT 5/21 and have just discovered they did not get filed ( even though I have all the final TT form instructions re payment and bank info listed.) I want to refile electronic but my existing forms having been completed as noted and won't take me to the final (re)filing steps. I don't want to reenter all info. How do I transfer the completed forms to a new submission, ie just move the data to a new TT filing?

My 2021 tax filing has been rejected twice because the "AGI amount from prior year is not correct in identifying me".....of course, there is no prior year on record.
