After you file

Last year, tax year 2019, because I owed money, I filed a paper return.  So, this year, when I tried to e-file, not having a PIN from 2019 to enter I was asked for my AGI.  I looked up my AGI entered it and electronically filed.  My return was rejected with the message that my AGI was incorrect -- it wasn't.  My guess is my 2019 return has not been entered into the system. Does that relegate me to filing a paper return, even though I should be receiving a refund?
