After e-filing my TurboTax 1040 return, how can I see the detail that went into the return? i.e. how can I see the detail of what I entered into the Itemized Deductions?

You may log back into your return and when you reach the landing page, scroll to the bottom of the screen and select Add a State. This will allow to go back into your return to review what you entered. Here go to federal>deductions and credits and then review all the itemized deduction entries you made.
