Maybe a you might talk to a tax preparer? I thought there was a line on the 1040 for “other income”?
Every option you check under 1009-misc comes up with the same message: "Congratulations! The payment you received from A and B Tennis Camps is considered business income to you. This means you own a business even if you received payments from only one payer."
It really isn't much but it will be used to skew the "new businesses" claim by the feds.
