This is still an issue with TurboTax, now one year later. Trying to file 2020 taxes for deceased father-in-law thru e-file, and rejected for AGI and pin # not matching. I cannot make them match because father-in-law was always the primary filer and now mother-in-law becomes the primary filer, and the AGI and pin cannot match. Very frustrating to have to resort back to paper filing.
