TurboTax didn't ask if the distribution was rolled over into another retirement account, like your 401(k). Where can I check or enter manually?

Have you entered the Form 1099-R?  If so, after entering the 1099-R there will be a series of screens asking questions.  One of the screens will ask if you rolled over the distribution to another tax deferred account.

If the Form 1099-R has code G in box 7 and you indicate in the questions that follow that it was not rolled over to any type of Roth account, TurboTax automatically treats it as a nontaxable rollover to another traditional retirement account.
