Thank you for your response. A follow up question, please.

 

If you have items on Mercari continually and sell one or two items a week, does that make a difference if it is continual? To be specific, I listed over 800 items over the last year (records, baseball cards, etc) and they sell according to when someone buys them. I will get a 1099-K and just want to make sure I shouldn't ignore it. Thanks again.
