First enter your 1099-R in TurboTax the same as you would if you did not have a QCD. After you enter the 1099-R proceed through the interview. It will ask you a series of questions about the IRA distribution. If the 1099-R has distribution code 7 or 4 in box 7, the IRA/SEP/SIMPLE box is checked on the 1099-R, and you are over 70½ years old, you will come to a screen that says "Transfer to Charity?" On that screen you can indicate whether the entire distribution or only part of it was paid to the charity. If it was part, it will then ask you how much. These screens don't say "QCD," but that's what they're about. After you enter all the information you will get a screen that tells you it's a QCD.
