line 8+line 9 on the 1099-B should equal line 11. if they don't talk to the broker
line 11 from the 1099-B, since it's a loss, is entered as a negative number on line 11 in the Turbotax screen.
that should do it with nothing in part II or III of the 6781.
if there are you may have answered question(s) on a previous screen incorrectly.
