E-file rejected
I received an IRS Notice CP80 indicating I had a credit on my account, but that I had not filed my return for 2020. I called IRS and was told my return for 2020 had not been processed, but that the check I used to pay my 2020 taxes had been received and cashed. The IRS person I talked with checked and said there were no problems my return, just that it had not been processed. I told the IRS person I was E-filing this year for a refund. The person told me do NOT enter an AGI figure on the return because IRS would not be able to reconcile it with the 2020 return. My 2021 return was rejected because the AGI for my wife, who is deceased, was missing. How do we fix this?
