Get your taxes done using TurboTax

It sounds like you engaged in personal item sales.  This TurboTax Help states:

Each gain or loss from a personal item sale needs to be reported separately. If you had a loss on the sale of any personal item, it cannot cancel out any gain on the sale of another personal item.

You would report the amount of payment reported on the IRS form 1099-K(s) that you received.

Amounts that are reported as "I sold some items at a loss or had no gain" are reported at the top of Schedule 1 Form 1040.

Amounts that are reported as income are reported 

• on Schedule D of the Federal 1040 tax return, and 
• on line 7 of the Federal 1040 tax return.

Capital loss for a personal item sale reports $0 capital gain on line 7 of the Federal 1040 tax return.
