Federal return E-file rejected code IND-031-04. No error was found on AGI and never e-filed before this year. Repeat e-file also failed. What else can go wrong?

AGI matches with mailed in returns from last year.  What else is used by IRS to verify identity?

There is a possibility that the IRS has not completed processing of your 2019 tax return.

Enter a 0 (zero) for the 2019 AGI and e-file the tax return again.
