Ebay 1099-K and cancelled (refunded) transactions

I sold several new items on ebay last year...a printer, laptop & vacuum. I was in between jobs and having cash flow issues. They were new in box (not used) which I had laying around and wasn't using. I plan to file it as Other, because I'm not a regular seller (Self-Employed), but these were new and not used "Personal" used items.

 

The other half of the story...the laptop & printer sale(s) were both cancelled & refunded by me, as both buyers used unverified / international drop shipping addresses which I did not feel comfortable shipping to. The only successful transaction was the vacuum, which was about $60 +$45 shipping. The laptop was about $400 & the printer about $200. I'm using TurboTax Deluxe. How do I report the 1099-K as "Other", and then enter negative adjustments for both of those items?
