As a freelancer in the entertainment industry, as a performer, where can I write off the money I spent on marketing/job related supplies? What section?

Assuming you are not an employee and receive a 1099-Misc for the income you earned, you would enter this information as follows:

1. Select the Federal section in the left panel
2. Select "Income & Expenses"
3. Select "Self Employment income & expenses"
4. Add your information in this section.  

You will report all of your income and expenses in this area of the return for your freelance business.  I have attached additional information to help you determine which items are deductible expenses.
