Was audited in 2019. They returned more that what was declared on line 20 & 20a of 2019 tax return. 2020 electronic filing required 2019 AGI. 2019 Filing was Joint (spouse died in 2019) Since I don't know what they calculated as new 2019 AGI to have increased my return How can I find the Adjusted 2019 AGI they used ?
