Hi I found this in TT
"FORM 1099-R, BOX 2a: TAXABLE AMOUNT
Generally, the amount shown in box 2a is the amount of the distribution that is taxable. However, if the payer is unable to reasonably obtain the data necessary to compute the taxable amount, this box may be blank and the "Taxable amount not determined" box in box 2b will be checked. For pensions and annuities, if the "Taxable amount not determined" box in box 2b is checked, the gross amount of the distribution in box 1 will be used as the taxable amount if box 2a is blank."
So do you think I should amend 2020 and 2021?
