Where do I declare that my IRA RMD was donated to charity in the online version?

[VolvoGirl]

Did you make a QCD directly from the IRA?  the IRA has to send it directly to the charity or send you the check made out to the Charity.  

You should have a 1099R for a QCD.  While entering your form 1099-R, if you have entered a birth date which makes you older than 70 1/2 in the tax year, TurboTax will ask you if any portion of your distribution was transferred to charity. You can then enter the amount transferred to charity.

Enter a 1099R under
Federal Taxes (Personal for Home & Business)
Wages & Income
Then scroll way down to Retirement Plans and Social Security
Then IRA, 401(k), Pension Plan Withdrawals (1099-R) – Click Start

The code in box 7 of form 1099-R must be 7 and the box IRA/SEP/SIMPLE must be checked.  A IRA QCD should be 0 taxable on 1040 line 4b and QCD written by it.  Unless you have other 1099R taxable amounts on 4b.

You have to enter the Form 1099-R and you have to select IRA/SEP/SIMPLE and the code in box 7 should be a 7 and you have to be age 70 1/2 or older.

After you have completed the Form 1099-R entry there will be a series of screens asking questions.  One of the screens Do any of these situations apply to you? check the box I transferred all or part of this money directly to charity

Do I itemize my 1099R RMD charitable donations in my donations portion of TurboTax as well as checking the box in the 1099R and filling out the questionnaire?

[SusanY1]

No, you do not itemize these donations.  They directly offset your income (a better result for you) after you indicate that it was a QCD in TurboTax by following the steps DoninGA has given.
