To report this distribution split to different types of destination accounts you must split the Form 1099-R into two for entry into TurboTax, one for the portion rolled over to the traditional IRA and the other for the portion rolled over to the Roth IRA. Assuming that the amount rolled over to the Roth IRA was equal to or greater than the amount in box 5 of the original Form 1099-R, you would allocate the box 5 amount to the 1099-R form you create reporting the rollover to the Roth IRA.
