What does depreciation have to do with the standard mileage deduction?
Answer JP: It does not have anything to do with mileage deduction. It is getting information to determine which is best for you mileage or depreciation. On the other hand, It also depends on how you have approached the question on TURBO tax. If you stated that you exchanged one vehicle for another vehicle it may be attempting to recover some written off miles. Other wise, as long as you have not written off more than a 100,000 thousand miles at the standard mileage deduction should be no effect on your final return.
