The standard deduction is a fixes amount so there is no reason to display it other than on the 1040 form.
You can check the actual amount of itemized deductions if less than the standard if you want to see it by using the Search Topics for "itemized deductions, choosing" (under "My Account, Tools" in the online versions). Click on "Change my deduction". That will display the actual amount of itemized deductions vs. the standard deduction. (Be sure to uncheck "Change my deduction" after checking it so you do not lock in the wrong deduction.
