Get your taxes done using TurboTax

I filed my 2019 taxes via mail.  Consequently, the IRS does not have an electronic record of my AGI.  Is there is a way to fix this on my 2020 return which I am trying to e-file.  Your directions on how to fix this are really so incomplete so as to be useless.  I can always file by mail, but would like to file electronically.  Is that possible this yaer since I filed by mail last year?  Hopefully you can give me a clear answer.
