When entering a code-G Form 1099-R that reports a direct rollover and you answer No to both questions regarding rollovers to Roth accounts, TurboTax automatically treat the distribution as having been rolled over to a traditional account, no need for other questions.
What TurboTax prompts are you talking about? They are not all for Roth IRAs.
What is the distribution code on your 1099-R?
In the screens after you enter the data for the 1099-R, eventually you will be asked, "what did [name] do with this money?"
Check "[name] moved the money to another retirement account."
Then in the new lines that appear, tell TurboTax if some or all of the distribution is a rollover to a traditional IRA or other retirement account.
This will complete the rollover.
