My Federal Tax return was rejected by the IRS because my 2019 AGI doesn’t match with my 2020. I can’t seem to fix the problem.
Be sure to use the 2019 AGI from the original return, not an amended one.
If it's a joint return, both spouses use the same total 2019 AGI--do not divide or otherwise allocate.
Did you file the 2019 return late in the year (such as mid-November 2020 or later), or was there an unusual delay in processing your 2019 return? And if so, did the IRS not finish processing your 2019 return prior to November 2020? In those cases one can try using a 2019 AGI of 0 (zero.)
