Won my fantasy football league and league members banned me from yearly league banquet. Please help?

You can list the income under other income. You do not have to declare the source. What you did was very offensive, and very insulting. They probably thought you were going to report them all for some offense to IRS. Most people do not understand the tax law and are very afraid of the IRS. I would think about joining some other club if I were you. You are a bull in a china shop. I would never let you belong to my club.
