Using step-by-step resulted in some rollover money being listed as taxable income. I needed to manually correct the 1099R on steps B5 and B6. For 401K rollovers to a ROTH IRA, the program should also ask if the entire amount was converted to a ROTH IRA and if not, then ask for the amount rolled over to a ROTH IRA. If the remaining money (distribution minus ROTH rollover) was rolled over to an IRA, that money should not be taxable. (I have the CD version.)
If you did a split simultaneous distribution and rollover, with some amount going to a traditional IRA and some going to a Roth IRA, TurboTax instructs you to split the Form 1099-R into two, one for the portion rolled over to the traditional IRA and the other for the portion rolled over to the Roth IRA. The dollar amounts on the two split Forms 1099-R must total the dollar amounts shown on the original. All other entries on each of the split Forms 1099-R should be then same.
