1099-K for reunion ticket sales balanced by expenses

A few issues with Eventbrite's 1099-K for proceeds from ticket sales to my high school reunion:

 

1. The 1099-K lists 2024 sales; sales in 2023 did not reach the reporting threshhold.

2. Proceeds were used to pay vendors, and the surplus was donated to the school's Alumni Association which is a 501(c)(3) resulting in a to-the-penny wash.

 

So the 1099-K figure is entered, but I also want to enter the expenses and donations. Where and how? And since 2023 sales aren't listed on this 1099-K, will the resulting "deficit" be a red flag?

 

Thanks.
