I am preparing a Form 1041 and on the Schedule D there is a Exception Smart Worksheet. I entered all the info I needed to and it has a place for as many single letter codes that apply. I entered Short Term, then Long Term, separately, but I guess they can be entered as one transaction. I put Code M in the Short Term, Code MW in the Long Term. I didn't see this Smart Worksheet for Form 1040 though. Hope this helps and hope I did it correctly.
