Schedule K-1 Questions

I had a small interest in UNG which was bought and sold at a loss of a few hundred dollars. This was entered in my 1099-B when I filed my taxes. However, I just received a Schedule K-1 (form 1065) regarding the same sale. Do I need to file an amendment? I'm very confused by the questions that TurboTax asks me and don't see all of the inputs listed on the Scheudle K-1. I'm thinking that if I enter the loss again on the K-1, it will essentially be reporting the loss twice, and so it should not be entered again. Can you provide some insights as to how to handle this Schedule K-1? Thanks in advance.
