Form 1040 line 4b will show the word ROLLOVER if you indicated to TurboTax that you moved some of a distribution to another retirement account or back to the same account.
(It's unlikely that you have a Form 1099-R with code G in box 7 and the IRA/SEP/SIMPLE box marked. Such a rollover from a traditional IRA to a qualified retirement plan at your employer is rather rare and, if an you actually did such a rollover, it's even less likely that you would have any question about it.)
