Solved
I donated 5000 of my IRA for a QCD. Tubotax won't accept 0 in the taxable blank., even though I have described it as a QCD in the following questions.
For a code 1, 2 or 7 Form 1099-R with the IRA/SEP/SIMPLE box marked, box 2a must always have the same amount as is in box 1. As TurboTaxColeen described, you'll indicate in the follow-up questions after entering the Form 1099-R details that you had some or all of the box 1 amount transferred to charity. TurboTax will exclude the QCD amount from the amount on Form 1040 line 4b and will include the notation "QCD" next to the line.
