The following diagnostic is generating: The year of the spouse's date of death must equal 2021 or 2022. Problem: I'm posting this in May 2024. In the situation of a taxpayer death in 2023 and a late filing of 2021 and 2022 tax returns, the diagnostic appears and prevents electronic filing. What is the solution? I'm tempted to input a DOD in 2022 to resolve the diagnostic. Would that cause a delay in processing by the IRS?
