I'm trying to report an installment sale that a sub s corp has.  The amount of gain is reported on the shareholder's K-1 and on form 6252.  Even when I link the 6252 to the K-1 both the gain from the K-1 and the gain from the 6252 get transferred to schedule D and is included twice on form 1040.  The only way I can get the results I'm looking for is to omit entering the gain amount on the 1040 K-1 form.  What am I doing wrong.  Thanks in advance for any input.
