You report the 1099R just as you have it, then if you have RMD and it was directly donated to a charitable organization, after the 1099R entry you will enter the amount of the QCD and that amount will be excluded from income.

There will be questions following the 1099R entry.

To add the above is only true if you have RMD which means you have to be at least 70 1/2 years old. If not the QCD is not available to you and TurboTax will not give you this option.
