Our tax software automatically updated our 2020 tax return to correct it, i.e., treating our unemployment compensation as nontaxable, without our even needing to amend our tax return or even log in to update entries. This update was made after our return had already been filed, so slightly confusing, since I still don’t know which AGI to report (since the IRS has stored the original, higher amount including unemployment as taxable income, whereas the adjustment made- that apparently didn’t get reported on the IRS data retrieval tool- reports a lower AGI due to exclusion of nontaxable income.)
