generally, column 8 is not 1250 but ordinary income reported on form 4797 line 10 (should be indicated on sales schedule) how to enter this. but from what I can see you need to do the following. on the sales supplement of the k-1 show the sales proceeds as the ordinary income (line 5 and ordinary income (line 9). do not report the capital gain/loss here.
the 1099-B will be wrong in that the cost basis will be what you originally pay not your adjusted tax basis. you'll need to adjust this so you come out with the capital gain as shown on the sales schedule.
