Business & farm

Trying to delete a K-1 for a partnership that was dissolved several Years ago. I have followed the directions by going to the section where I am asked if I received a K-1 and did was the instructions said but it is still there. I then went to Tools where the instructions said to click on Delete Form in the drop down menu but there is no such link. How do I get rid of the form and all associated forms if those two directions don't work?
