Survig,
Sorry, I see you issue is about a Canadian RMD, not a mutual fund dividend with foreign tax withheld reported on Form 1099-DIV. I do not even know what Form a Canadian RMD with withholding (by presumably the Canadian government) would appear on. The long post on page 24 of these posts may, nonetheless, be helpful to give you an idea where things specific to your issue may have gone wrong in Form 1116.
