Does anyone know where a dollar amount in Sale of Business Property would come from when there was no such sale made?

There is a dollar amount showing up under Sale of Business Property. When I go to edit it, I check that there was no such sale but there is still a dollar amount there. I don't know where to look to find an error. It should be $0.

Maybe from a Schedule K-1.
