I'm an independent contractor for company that pays me through Paypal. I received cashback to same Paypal from Ebates & sold items on ebay, Paypal sent me one 1099-k?

 I also sold a couple video old video games too which is also included in the 1099-k. Paypal has never sent me a 1099-k before. Am I supposed to pay taxes on the cashback and three used video games I sold on ebay?

 (I always received a 1099-misc from the company but they didn't send this year because Paypal sent the 1099-k)


Edit: I'm in MA and saw there is a new law that my state requires a 1099-k now but still unsure about the cashback and ebay sales
