Based on your facts, it appears that you have entered this twice somehow. Capital gain and/or losses from a K-1 should only be reflected on Sch D line 5 or 12 as applicable.
In addition, your facts are not real clear. Is the loss from the sale of stock that the S corp held or are you saying that this is a loss on you selling your S corp stock. If the former, then this makes sense. If the later, the K-1 is not correct.
