Deductions & credits

As I've stated several times, I know I cannot write off mileage on a vehicle I do not own. So I wish people would stop pointing out the obvious to me. I get it. The problem is that when I go through the "interview" on TurboTax, it only gives me TWO choices: Own or Lease. That's it. No option to say, "Hey, I don't own this car." The problem remains.
