See the Instructions for Form 1099-R and 5498: <a rel="nofollow" target="_blank" href="

The box 1 amount being replicated in box 2a is meant to suggest that in most cases the entire distribution is taxable. In the case of a QCD, that's not the case, so what maglib described is what is required for reporting a QCD in TurboTax to make the QCD amount nontaxable.
