Turbo Tax Review says my "vehicle depreciation allowed or allowable is too large". Sold the vehicle in July 2020 after using it 6 years for business. I have no idea what or where to make changes. Looking at the form (Car and Truck Expense worksheet) doesn't help as the line in red isn't something I can edit. (line 51)
Also, did some prep work on the car in the process of getting ready to sell. Could that be a cost of sale expense instead of the normal business expense for the car? (Oil change, smog check, and a couple of maintenance items).
TurboTax is NOT set up to report the sale of an asset (such as a vehicle) that has varies in business percentage from year to year. It has problems on several levels.
You may want to go to a tax professional this year to properly report that.
