Business & farm
You should be able to enter 0 for Business Miles driven. If you indicated you 'stopped using the car for business' you will be asked for a date you sold, traded in, etc.
If you didn't use the vehicle for business at all in 2022, and entered 0 for both mileage sections, you may get a Review error, but should be able to continue past it.
If you indicated you use the vehicle for both Personal and Business, you may need to enter a 'Total Miles Driven' number in any case, so TurboTax doesn't think you stopped using it; you just didn't have any Business Miles to enter.
If you're using TurboTax Desktop, you can make the entries directly on the Vehicle Expenses Worksheet in Forms mode.
