TurboTax asked the dates I lived at a location. I lived at the same location the entire year and so put in the state+local combined tax rate. However, I purchased a car in a different city which has a much higher tax rate (1.4 percentage points higher). However, it won't let me take credit for all of the sales tax I paid, unless I lie and say I lived in that city for a day, and I absolutely won't lie to the program.
"Taxpayers also may add to the table amount any sales taxes paid on:
A motor vehicle, but only up to the amount of tax paid at the general sales tax rate ...
For example, the State of Washington has a motor vehicle sales tax of 0.3 percent in addition to the state and local sales tax. A Washington state resident who purchased a new car could add the tax paid at the general sales tax rate to the table amount, but not the 0.3 percent motor vehicle sales tax paid."
