1099 K

Hello,

 

I received a 1099-K from Ebay because I sold a few thousand dollars worth of action figures from my personal collection I had from 1998. Last year I was told to enter the amount of money i paid for shipping for 2021. I dont see where to enter the amount i paid for shipping last year.  Do i deduct the shipping i paid for last year? if so, how do i do that? ( i have the deluxe version)

 

Thank you
