I live in a county in Washington state that has a sales tax rate of around 8.9%. I purchased a car in a different county that had a combined city, county and state sales tax rate of 11.7% on vehicles. When I enter the price of the vehicle (minus trade in an excluding tax) and then enter sales tax paid turbo tax only allows me 8.9% deduction even though I paid 11.7%. How do I fix this as the rate used to compute standard sales deduction excluding major purchases, various from county to county? I am losing out on about $600.
