I'm not sure why you expect Schedule 1-A to "pop up," or what exactly you are expecting to see. You do not have to enter anything to get the deduction for seniors. TurboTax gives it to you automatically, based on the birth date that you entered in your personal information. If you are using TurboTax Online the only way to see the actual Schedule 1-A is to print your tax return.
The deduction for seniors has nothing to do with your Social Security income. It's a separate deduction from your overall income.
