There is no question that TurboTax asks during the entry of the Form 1099-R that indicates whether or not the distribution is from a SEP IRA, so there is no way for TurboTax to block the reporting of a QCD from a SEP IRA.
If your personal information indicates that you were age 70½ or over during the tax year and the Form 1099-R that you received from the payer has code 7 (or code 4 if the distribution is from an inherited IRA) in box 7 and the IRA/SEP/SIMPLE box marked, in the online version of TurboTax TurboTax will provide a checkbox on the Do any of these situations apply to you? page for you to mark to indicate that some or all of the distribution was made as a QCD. In the CD/download version of TurboTax TurboTax will explicitly ask if any was paid to a charity.
