TurboTax is unable to handle a single Form 1099-R reporting a distribution that was split into separate rollovers to traditional and Roth IRAs. You'll need to split the Form 1099-R into two, one for the portion rolled over to the traditional IRA and the other for the after-tax portion rolled over to the Roth IRA. The dollar amounts in the boxes of the two split Forms 1099-R must total the same amounts as in the corresponding boxes of the original Form 1099-R. Only for the split Form 1099-R reporting the portion rolled over to the Roth IRA will you indicate that it was rolled over to a Roth IRA. For the portion rolled over to the traditional IRA you'll indicate that you did not roll it over to any kind of Roth account.
