According to Kiplinger Tax Advice, the prior answer is incorrect. Per Kiplinger: The first dollars out of an IRA are considered to be the RMD until that amount is met. If you want to do a QCD of $10,000 that will count toward a $20,000 RMD, be sure to make the QCD move before taking the full RMD out.

I have seen different answers to the original question so get your own tax advice from a professional tax advisor.
