I was VERY frustrated by the TurboTax solution for this issue. I downloaded the transcript and had my 2019 return in hand with the same AGI. I had the same problem last year and finally mailed both federal and state. It took IRS until Feb 2021 to send my refund!! Almost exactly one year from filing. So, this year I was going to find the solution. Here's my success .
I went to irs.gov and created an account for both of us individually. Then I requested a new ID PIN number. for each of us. I revised my 2021 form (by signatures); go to "more tax information" in TurboTax to edit. Then I resubmitted by their directions It says IRS will issue you this PIN but you also request one.
And it worked both federal and state were accepted within the hour! I wish TurboTax would further share this solution.
