Qualified Charitable Distributions

I am replying to myself since I didn't have an opportunity to actually post anything. 

Here's the problem.  I have several accounts from which I receive RMDs.  In some, the RMD and the QCD are the same, so the taxable amount is 0.  TurboTax gets balled up when I enter zero in the taxable - gives an error re needing prior excess traditional IRA contributions when I run the final error check.  It also seems to double the amount of the QCD though I'm not sure about that.  A different account in which the RMD and the QCD are not the same has no problem when I enter the RMD minus the QCD amount in the Taxable box - no error and it gets the QCD amount correctly.
