Should I enter my vehicle as a business vehicle or personal vehicle if it was occasionally used to go to job sites?

You would add your car using the “Add A Vehicle for Business Use” button. You would only use the “Add A Vehicle for [Your Name]” button if you were in a partnership and you were using a car that wasn’t owned/shared by the partners.
