E-file Rejected for AGI

My e-file has been rejected twice for an incorrect AGI.  I downloaded my 2020 IRS transcript and have confirmed the AGI I used to verify my 2021 e-file.  I also confirmed my 2020 e-file was accepted by the IRS.  A Turbotax agent told me yesterday that there's an investigation into this problem and that I should wait until I hear back from Turbotax before I try to refile.  However, I received an email from Turbotax hours after that call that says "If you are sure that your AGI is correct and are still receiving this error you may need to mail it in."   There was no mention of an investigation or that I should wait to refile until I hear back from them.  I'm using their Self-employed download software.

 

Is anyone else getting an IRS e-file rejection for an AGI that you are 100% sure is correct?    Has anyone else who has the same issue been told an investigation is ongoing into it and not to refile until Turbotax gives the go-ahead?
