How can I get a standard deduction for the use of my vehicle for business? I have been claiming it since 2015 but turbo-tax defaults to manual?

Once you’ve used the actual expense method for a particular vehicle, you are required to continue using that method to calculate vehicle expense deductions in future tax years. 

. The standard mileage rate cannot be used if you:

• Use five or more cars at the same time (as in fleet operations).
• Claim depreciation or a section 179 deduction (Publication 463, Chapter 4).
• Are a rural mail carrier who receives a qualified reimbursement (Publication 463, Chapter 4).
