Confusion about 1099-K filing with eBay/at a loss?

So I received a 1099-K from eBay after selling some personal items like clothes and old shoes and books at a loss & I’m wondering how to file it? I didn’t realize how MA laws changed this year and that I would be sent one automatically if I sold over $600 dollars complicating how I normally file things. I don’t know how I should file it as I’ve taken a loss in things and I’ve been selling things just to get them out of my apartment : /
