I used the percent sales tax rate for my state AND the tax on a new car in the same year but turbo tax only shows the amount for car - why won' it show total for both?

TurboTax calculates both the sales tax paid to your state and local government as well as the sales tax paid for certain major purchases like your car.  Follow these steps while in TurboTax Deluxe to correctly claim the deduction:

1.     From the Federal Taxes tab, go to the Deductions & Credits section.

2.     Scroll down to Estimates and Other Taxes Paid. 

3.     Click on the button to the right of Sales Tax (Start or Update).

4.     Click Continue with Sales Tax.

5.     Select EasyGuide.

6.     Click the Edit button (omitting this edit will omit state/local sales tax paid).

7.     Enter the dates you lived in your state(s), click Continue.

8.     Enter your combined local and state sales tax rate, click Continue.

9.     Click Yes to enter information about your major purchase.

10.   Enter information about your major purchase, click Done.
