For example, I use 200 miles for business, and 300 miles for rental, and 500 miles for personal purposes.
It seems that if I put vehicle expenses on both places - (20% usage for business and 30% on rental keep all other costs such as registration, car repair, etc the same), Turbotax treated my car as two separate cars... The depreciation seems not correct in this case (I prefer using actual expense since this will give me a bigger return).
