Form 8800 Line 1

I am REALLY confused.  Turbotax is automatically placing the amount shown on my W2 in box 12 AA onto line 2 of the 8880. That seems correct.

 

It appears that money I place into a traditional IRA or Roth IRA in addition to that amount (outside accounts I set up somewhere) gets filled in on Line 1 of form 8800. But when I am on the TurboTax page where it says "After tax additional contribution", if I click on "Learn More" a popup box instructs me NOT to enter traditional IRA or Roth IRA amounts in the box. I was assuming these were the amounts that would be placed on Line 1 of form 8880.  So my question is this. If in addition to my contributions to my work retirement shown on the W2, if I do get credit for additional deposits I make on my own to an IRA or Roth IRA where do I enter it in Turbo Tax Desktop 2021?
