State tax filing

It depends.

If you are able to itemize deductions and if your sales taxes are higher than your state income taxes, you could potentially take a deduction for the sales taxes.

You can make this change in the federal section of the program.

1. Select Deductions & Credits
2. Scroll down to All Tax Breaks 
3. Select the section titled Estimates and Other Taxes Paid
4. Select Sales Tax
5. The first screen titled Let's Compare Your Sales Tax and Income Tax will give you the recommendation from TurboTax, but you can select to try the other deduction
6. Continue to enter your information as prompted. 
7. You will eventually reach the screen as shown in the sample below titled We've Chosen a Deduction for You.
