TurboTax personalizes the list of expenses that it'll ask for depending on the type of business you have. I would suggest that you go back to the questions regarding your business and make sure that you entered the correct type of business. Generally, if it is a business that carries inventory, the program will ask you all the necessary questions to calculate your COGS. To get back to your Schedule C:
- Open or continue your return
- Locate the Schedule C section
- Go to Schedule C
- Under the business you need to review, go to Review
- Change your Work description if needed
- Once make the change, continue the interview until you get to the expense categories (see the image below)
- Select Inventory the program will guide you as you enter the information. If it doesn't come up, you can try at the end under "Less Common Expenses."
