I'm trying to enter my Lyft Express rental cars into the section where I can deduct my gas expenses, but I keep getting an error message. What am I doing wrong?

It asked for the date that I "sold or stopped using" the car and I put in the date that I returned the car to Hertz. A message came up at the end of the section that I can not put in a sold date for a car that I didn't own. I tried removing the date that I stopped using the car, but I was still unable to get passed this section.
