I am trying to put the interest I paid on my car. Is that the same as the finance fee I paid on my loan?
Yes - If your vehicle is used in your business you can deduct the business portion as an expense. To do this, please follow these steps:
Click on Income and Expenses and then click the Start/Revisit box in the Self-Employment section.
On the Here's your [business] info screen, click on the box Add expenses for this work.
On the Tell us about any expenses screen, scroll down through the categories, mark the radio button next to Credit card, loan, and other interest and click Continue at the bottom of the screen.
After entering information on that expense, you will be returned to the Expenses screen so you can select another expense category.
