A From 1099-R for a direct rollover from a traditional account in a 401(k) to a traditional IRA should have code G in box 7, the IRA/SE{/SIMPLE box unmarked and a zero in box 2a. After entering such a Form 1099-R into TurboTax and answering No to both questions asking about rollovers to Roth accounts, TurboTax will automatically treat this as nontaxable income, included on Form 1040 line 5a but excluded from line 5b with the ROLLOVER notation.
