I decided to redo my Form 1116 entries for the one return that is having issues.  It appears that I had some discrepancies with how I inputted data due to having foreign tax paid from Form 1099-DIV and a K-1 from a trust.

After reentering all data, my return was accepted by the IRS.  I think in this case, it was user error, although it would have been nice if ProSeries itself would have flagged the issue prior to filing.  I had no ProSeries errors.

Good luck to whoever still has Form 1116 issues!
