Deductions & credits

I'm definitely in the business at this point. I've got a 1099-k, but as I go through the steps in turbotax, I'm just confused as how I enter the vehicle and mileage. The way I'm doing it now, is by adding the two vehicles to this business and then using a standard mileage deduction, including the parking fees, fees turo charges me, etc. I'm showing a massive loss on paper which is helping my taxes owed, but I'm just not sure I've set it up correctly. The way I read it is that I'm driving all those miles, not that I'm renting the vehicle out and I'm not sure if that is the correct way to do it.
