I don't believe that marking a vehicle as no longer used for business - when the break in use may be temporary - is the right solution. I don't see a reason that the Car and Truck Expenses Worksheet shouldn't be able to handle the situation where zero miles are driven for business in a given year. In past years, this hasn't been a problem - TurboTax happily accepted zero business miles on the Car and Truck Expenses Worksheet.
As the OP noted, removing a vehicle from business use makes even more work - additional fields that need to be filled out to decommission the vehicle from business use, plus re-adding the worksheet in the future if the vehicle is again used for business.
When will TurboTax be correcting the Car and Truck Expenses Worksheet to accept zero for total business miles so that we can retain the worksheet with the return for future years?
