Business & farm

I am trying include my eBay inventory that sold this year COGS to write off on my gross income. So I was understanding that I could choose not to keep an inventory and put my 2022 COGS under non-incidental materials and supplies. Whatever remains unsold on the shelf, I will deduct that Cost of Goods in the future year it sells. Is this correct? If so not sure where to input it on TurboTax.

 

Would I select Cash accounting or accrual.
