Because the sales tax is an itemized deduction you cannot use the free version to claim it.
In other versions, the deduction for sales tax is under
the deductions and credits tab. Go to:
- Deductions and Credits
- Estimates and Other Taxes Paid
- Sales Tax.
- Click Update next to Sales Tax.
- Click Continue.
- Select Easy Guide
- Click Edit next to your sales tax rate.
- Click Continue twice and you will then be on the page where
you enter your car or other major purchases.
