You should have received a Form 1099-R for the distribution from your IRA. After you enter the information from the 1099-R into TurboTax, 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 70 1/2 years old, you will come to a screen that says "Transfer to Charity?" On that screen and the next, you will indicate how much of the distribution was sent to charities.
