The excess SS taxes are entered on Schedule 3 Line 11.  The totals from Schedule 3 Part II Line 15 flow to Form 1040 Line 31 as a tax payment.

You can view your Form 1040 plus Schedules 1, 2 and 3 at any time using the online editions. Click on Tax Tools on the left side of the online program screen. Click on Tools. Click on View Tax Summary. Click on Preview my 1040 on the left side of the screen.

It was probably already included before you noticed and it told you.  

Since you paid too much social security taxes because you had more than one employer, the excess will be reported on Schedule 3, line 11 of your 1040.

Refer to the TurboTax article Can I get a refund for excess Social Security tax withheld? for more information.
