The payer reports a QCD is reported as a normal distribution. You indicate to TurboTax that it's a QCD by marking a box to indicate that some or all of the distribution was transferred to charity (online version) or by answering Yes when asked if some or all of the distribution was transferred to charity (CD/download version).
A QCD only affects the amount reported on Form 1040 line 4a and requires the "QCD" notation next to line 4b. It has no other effect on your tax return.
