Just found this thread and experiencing the same anxiety. Similar operation to OP (Also a MA resident) except I've been buying and selling trading cards to support the hobby. Basically recycling the same money to the tune of 9k in 'income' on my 1099-K. Where do I claim the expenses without filing a Schedule C (because I'm not a business and have no profit motive). I got stuck on this last year and just neglected reporting it at all to Fed or State (did not realize I had to below the Fed threshold and the State one I didn't know was different until this year. That was less income though, only about 4k. Also a net loss/wash with the expenses I could have claimed)
TY!
