I lived in 1 city the entire year & pay no state income tax. I bought a car at a location that has a higher sales tax. How do I get the full amount of sales tax deducted?

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.
