If you can't figure out what is going on with your return to explain the error, we can tell you how to ask a TT Expert to review your tax data to see what happened. The way they do this is to ask you to upload a "sanitized" version of your tax file--i.e., one that has all of your personal information scrubbed from it when it is sent to them (scrubbed as part of the submission process--not by you.) You are then provided a token number to give to the TurboTax expert.
