Loss of Inventory Question

I work a chocolate company and the majority of my sales is through shows. After the shows the chocolate is only good for so long and I have to eventually toss some out. This being my first year in business I had to toss out alot.  Where can I account for those losses in Turboxtax.

 

Someone told me I couldn't but that doesn't really make sense as its lost product. Would it be under doubtful account? Or inventory "other costs".
