eBay 1099K Sales for a Loss

I sold a large quantity of items on eBay in 2024 for less than the purchase price resulting in a significant loss.   However, eBay sent me a 1099K showing the gross payments.   I have created a lengthy spreadsheet showing the item #’s, sale price, original purchase price, and some additional information regarding where purchased and receipt electronic location.  How do I go about filing this information so my 1099K total is not taxed as income?
