If a Roth IRA is moved to another Roth IRA by trustee-to-trustee transfer, where the money was never paid out to you as part of the process, it is not a reportable transaction. It is neither a distribution (withdrawal) nor a rollover.
If the Roth IRA was moved by the money in the original Roth IRA being paid to you and you subsequently deposited the money into another Roth IRA within 60 days, it is a distribution (withdrawal) followed by a rollover contribution. The distribution would be reported to you and the IRS on a Form 1099-R with code J, T or Q in box 7.
If the original account was instead a designated Roth account in a qualified retirement plan, commonly referred to as a Roth 401(k) , Roth 403(b) or Roth 457(b), a direct rollover would be reported on a Form 1099-R with code H in box 7. If it was instead an indirect rollover, paid first to you and subsequently rolled over by you to a Roth IRA, the code would be 1B or 7B depending on your age.
In TurboTax, other than entering any Form 1099-R for this and indicating that it was rolled over, there are no other areas of TurboTax where you would have to enter this "withdrawal."
