I have this problem with 2019 return. I logged onto IRS.GOV/transcript and confirmed that all my account transcripts have the same AGI I have in my records. I file Married filing jointly and the rejection says my spouse's AGI is incorrect. Turbo Tax does not ask for 2018 AGIs as identification in the version of 2019 software I bought at Costco. Short of standing in line at the local office, I don't know how to devine what number they want.
