Is standard deduction automatically applied?

I went through the interview process where I've added all my itemized deductions to determine if I should do standard or itemized. In the end TurboTax determined that standard was the biggest saving for me. However, The 'tax counter' didn't show a decrease when standard deduction was applied. I could see this counter decreasing for other deductions such as HSA deduction. Is standard somehow automatically applied to my owe/refund amount?
