To accommodate the limitations of TurboTax, you must split this Form 1099-R into two, one for the $200,000 rolled over to the traditional IRA ($200,000 in box 1, $0 in box 2a) and the other for the $50,000 rolled over to the Roth IRA ($50,000 in boxes 1 and 2a). Do a do-over by deleting the original 1099-R form from TurboTax and then entering the split forms, indicating the particular destination account for each.
