It is a Federal Critical diagnostic. Form 1116 schedule B - not supported by the program. It wants information manually entered into the return. I did that. Still hasn't gone away................................. PDF Attachment: Form 1116 Schedule B must be attached to the return, when Form 1116, Part III, Line 10 (foreign tax credit carryback or carryover) is not zero. At this time, Form 1116 Schedule B is not supported by the program.
