1099 K offsetting

Using 2024 Premier. I got a late 1099 K after I filed my taxes. The 1099 K was for $8000 that I received for a seat license fee (football tickets). But I paid $7700...so only $300 is taxable. The problem is I can't figure where to offset it. I listed it as Personal property. It either vooms my tax up to the full $8000 or I get errors on the error check saying numbers do not match. What exact entries and how do I get it to take the offset of what I paid for the license? Thank you!
