If you are entering sales tax paid, you have a choice to enter the totals from your receipts or to let TurboTax calculate an amount based on your sales tax rate and your income.
Sales tax is an itemized deduction. If your state has a state income tax, you have to choose between using the deduction for your state tax paid OR the sales tax deduction, whichever is higher. The TT process will suggest one or the other as you prepare your return.
