Final 1120-S Instructions for 2021 "Column (d). Other Adjustments Account The other adjustments account is adjusted for tax-exempt income (and related expenses) and federal taxes attributable to a C corporation tax year. After these adjustments are made, the account is reduced for any distributions made during the year. See Distributions, later. Tip PPP loans. An S corporation should include tax-exempt income from the forgiveness of PPP loans in column (d) on line 3 of the Schedule M-2. An S corporation should report expenses paid this year with proceeds from PPP loans that were forgiven this year in column (d) on line 5 of the Schedule M-2. If column (a) on line 2 or line 4 of the Schedule M-2 includes expenses paid with proceeds from forgiven PPP loans, an S corporation should report that amount in column (a) on line 3 and in column (d) on line 5 of the Schedule M-2. If column (a) on line 1 of the Schedule M-2 includes expenses that were paid in a prior year with proceeds from PPP loans that were forgiven this year, an S corporation should report that amount in column (a) on line 3 and in column (d) on line 5 of the Schedule M-2."

I would agree unless the distributions exceeded the AAA balance on the originally filed return then I would recommend filing an amended 1120S return for 2020, amending the 1099-Div and amending the shareholder’s personal return. I would also agree with your schedule M-2, line 3, column (a). Not sure what description I would use.
