Do I add a car loan to my return

No you do not enter your car loan anywhere on your tax return.

I bought a car last year, I paid some of it off in cash when purchasing and the rest was on a loan. I don’t add that anywhere when filing my taxes correct?

@lourdespulidol No, your car loan nor paying off the car is entered on a tax return.    You do not enter anything about your car loan unless you are using it for business.
