is there nothing in a cover letter or supplemental schedule or statement that mentions what to do with D? this is unusual because unless the tax basis was zero, there should be some effect on the k-1 and schedule L in part II.
If not, you need to contact the partnership so that D is handled properly for your taxes. There is the possibility that D was merged into one of the others so any carryover info would have to be transferred to the acquiring company's k-1. it might have been sold off and the k-1 reflects this. there are other possibilities each with a different tax outcome for you. post back in this thread if you need further guidance and include what you were told about D.
