TurboTax goes almost entirely by the code in box 7 of the Form 1099-R, except in the year that you reached age 59½ as indicated by the date of birth that you entered in which case TurboTax explicitly asks if the distribution was received before or after you reached age 59½ (but only uses your answer to determine what to do next and does not record the answer; if you revisit this question you must re-answer the question). If box 7 does not include code 1 or code J, the distribution is not subject to penalty.
