Deductions & credits

Yes, you can include those sales tax costs in your itemized deductions, but the income tax deduction might be lower.  Here's how you can navigate to the sales tax entry in TurboTax Online:

1. Navigate to Federal > Deductions & Credits > Estimates and Other Taxes Paid > Sales Tax > Start or Revisit

If you're itemizing, you must choose between deducting your state and local income taxes or your state and local sales taxes. You can't claim both.
