One other reason that TurboTax would not ask what you did with the money is if you indicated that all of the money was transferred to charity (as a Qualified Charitable Distribution); rolling over a distribution and treating it as a QCD are mutually exclusive.
Under the circumstances, even though code G with the IRA/SEP/SIMPLE box marked is to be used only to indicate a direct rollover from an IRA to a qualified retirement plan like a 401(k) (which is not what you did), picking code G instead of code 7 will give the correct taxable result. Substituting code G for code 7 should not be done if there was any tax withholding. For a code 7 Form 1099-R entered properly (without indicating that it was all RMD, without indicating that it was all transferred to charity and without indicating it was a distribution from an inherited IRA), TurboTax will ask what you did with the money. If it doesn't, you should delete and reenter the Form 1099-R (manually).
