Deductions & credits

Rogge THANKS, you certainly know your stuff. As you suspected I am not required to fill F1116 and that would explain the error. However, I still wish to make sure that I am doing the right thing: Should I manually enter into TT 1099-Div Worksheet box 6d the "Foreign income" (not listed in Vanguard's 1099-DIV, but available in another statement), 0 (zero), or it makes no difference (as the number appears not to carryover elsewhere)?
