Deductions & credits

You have to be in the Self-employment income section. As you are going through that section, it will ask if you used your vehicle for business, answer "yes" and TurboTax will guide you through to enter the information about your vehicle.

To get back to that section, 

1. click "Wages and Income" on the left panel, 
2. then "Self-employment Income"
3. Click "start"

Please note, you will have to upgrade to our Self-employment package in order to deduct business expenses.
