The amount of your Roth contributions should be in 5 of this Form 1099-R and the taxable amount in box 2a should be the amount in box 1 minus the amount in box 5. If the distribution was no more than the amount of your Roth contributions, the amounts in boxes 1 and 5 should be the same and the amount in box 2a should be zero.
TurboTax will include in income only the amount in box 2a even if no amount is present in box 5. If the amount in box 2a of the Form 1099-R provided by the payer is incorrect, obtain a corrected Form 1099-R from the payer.
