Self employed

Are you a tax professional? I thought this was ask a professional event. 

I'm asking what to do on my taxes when I possibly get 1099s for making $25k from ebay and PayPal from selling all of my stuff. Hope the tax man/woman will ignore and just not claim it, and somehow they'll assume it was garage sale sales? Is there a way to claim it was garage sale or the source -like selling all personal items?
