Turbotax treating remaining inventory as income.

I have a small wholesale car business but did not participate in it this past year due to health problems. My beginning and end of year inventory stayed the same yet when I enter my end of year inventory (the same as beginning) it deducts from my federal refund making it seem it is income. What am I missing or doing wrong?

 

Should I just not file a schedule C for last year as I had no income?
