Are you saying you want to do it the right way?  Then just attach the pages that show the post mortem transactions.  Add them up and just show the total on the 1041 Schedule D.  The problem you might have is with the 1040, where the transactions you report will be less than what is on the 1099-B.  I think there are some instructions on how to deal with these as "nominee distributions."

You really think anyone at IRS is going to look at whatever you attach to the 1041?  As they say at IRS, "ask me if I care."
