So I had a return finished the other day that had no errors, went to efile it, and the federal return was rejected.  Can't remember the exact language, but something to do with Form 2441 not being finalized for the six month or less provision and refundable CDTC credits.  I went to the form, clicked the box, and then was able to e-file the returns.

So maybe ProSeries will not flag this as an error, but it will stop you from e-filing the return?
