After you file

Unfortunately the above answer is about right and clear as mud. In other words TurboTax Home and Business does a terrible job. It basically makes it hard, hides QCD in a fog, and "help" is nearly useless.

Good luck, the hard work is worth it, but you are pretty much on your own.l

UPDATE: I apologize for my above comments NOT being helpful. Here is more practical information:

 

"As stated by expert DanaB27, the distribution must be from an IRA, the distribution code on Form 1099-R must be '7', and the IRA/SEP/Simple box must be checked in order for TurboTax to recognize that the distribution may qualify as a QCD. "

The QCD total is the total QCD contributions and only listed here and one time. The next box asks for RMD and as best I can tell is the total RMD amount which does not change and must not be exceeded simply because the allowable QCD can not exceed the total RMD for the year. As long as QCD is less than RMD, then the total amount of QCD is subtracted from income, AGI and all should be well. However, it seems to be hidden by TurboTax, so one way to tell is the amount of estimated taxes to be paid changes significantly. And do NOT list those charitable donations any other place, just keep your receipts. Best wishes!
