We got this same rejection when we tried to file our 2019 extended joint return in July. I am the spouse, and I’m very much alive, and getting the same error codes for prior year AGI or prior year spouse pin. Both pieces of data were saved in TurboTax from last year and have been double and triple checked. I have just tried resubmitting but since nothing was changed with regard to either of these pieces of information it will probably get rejected again. I just wanted to post this here so people would know it’s not just an error when there’s a deceased spouse.
