TurboTax carries some information over from 2020. If your daughter used the “wrong” car for DoorDash last year and switched to a new car this year, TurboTax will transfer the basic info about the old car into the vehicle section of your daughter’s business.
You would have to add a second car to get two cars there. TurboTax could not do this by itself, because it doesn't know anything about a second car.
You would see the old car in the Vehicle Summary and would have had to Add Another Vehicle to put a second car onto your daughter’s Vehicle Summary.
The Vehicle Summary also has a trash can to delete the “wrong” car on the same screen that you would use to add the second car.
