@Andrew Warner 

Putting any gain, or loss, on the purchase & subsequent sale of ASSETS on a Sch C is incorrect.  Doing it that way would either increase, or decrease self-employment income and self-employment tax.  

@Jessica Ly  - I suggest you put this return on extension, and find a local mentor to assist you.  While the numbers aren't large, the concept of what goes on Sch C vs the sale of assets is important.

You should also 'unclick' if possible the solved solution, for future searches as it is wrong.
