1099-K help!

I'm the Treasurer for our summer swim team program and received a 1099-K for all the membership dues that were collected. The 1099-k was issued using the bank account EIN that was set up and used for collection purposes. We are not a not-for-profit business and all dues are used for the program. Since this is set up with the bank account EIN and not a business, how/where do I report this income with offsetting expenses so that we/I am not taxed.
