TurboTax automatically entered Standard Deduction despite the total of itemized being higher. There is no Schedule A to compare or explain the choice.
It won't be in the forms list in forms mode. You must use the Open Form feature at the top of the forms list to open it.
You can switch to Itemized and then look at your schedule A. You may then switch back to Standard if you desire.
