If state has standard deduction amount, how does one import that number into state return, as never prompted to apply deductions?

TurboTax automatically applies the rules for the standard deduction for your state.  So, if you are not itemizing, then standard deduction amount for your state return gets applied automatically against your income.  There isn't going to be a prompt for you to enter.  

(Note that some states require you to take the same type of deduction as your federal return, some allow you to choose between itemized and standard for the state.  TurboTax will apply the higher deduction in these cases but you need to make sure you have entered all your itemized deductions in the Federal section as that is where the program will pull these numbers from automatically.)
