I've completed the information on worksheet for disposition of S corp interest: I checked the box for disposition other than by sale, entered date shares purchased, date shares "sold", zero sales price and zero selling expenses, and final basis figure (have tracked on 1120S and using ending balance on Schedule M-2 of that tax return).  These entries correspond to the actions to be taken per "help" for dispositions other than by sale, BUT the software isn't calculating the loss on disposition (i.e., owner's remaining basis of $25,616) as the help section indicates it will.  What am I doing wrong?
