Get your taxes done using TurboTax

I received a paypal 1099k because I sold old household items on ebay (at a loss).  I'm in Virginia where they have lowered the reporting threshold to $600.    I have read that sale of household items isn't normally taxable.   I'm not running some kind of resale business, just doing a household cleanup...every few years I try to sell some items.  So how do I report this? 

 

Suppose I actually made money selling household items.  That's supposed to be a capital gain reported on schedule C, not self employment.   Would I still have to list this on schedule C?  (I've never seen Schedule C.)
