I sold some items on ebay, I received money via PayPal. PayPal has recently given me a 1099K form. I've never had to do this before, I don't know how to report it

I went to go attempt to fill in the 1099K Form PayPal provided me, TurboTax instead told me "We don't need a separate entry for your 1099K. It should already be included in other income such as self-employment"

But this wasn't self-employment, just side things sold on ebay.
