How to change a loss from short term to long term

I can't see how to move an entered loss on my D and 8949 from short term to long term. Not sure why its there based on the dates I used but perhaps I entered the wrong link to get here. Is there any way to change it? I don't see how to delete the 8949 either, it just comes right back, and I can't delete the entries from the D. So what's the trick here, isn't there a code somewhere that can just be changed?
