Self-Employed Rental Car Expenses (Gas, tolls, and parking)

[notanumber]

I've had to rent a car to work on-site with a client or for meetings. I believe the business portion of the rental can be entered on line 20a of Schedule C. Would operating expenses such as insurance, gas, tolls, parking etc. be entered on line 20a or elsewhere?

Thanks in advance.

You can put it all on line 20a, or you could put the parking, tolls, etc. on line 9, or 27a.

Thanks, that's simple enough.
