Where do I enter if I paid more mortgage interest than is shown on my form 1098

If I click on Learn More, I am told to enter the total "below" but there is no space/box that exists below. I expected a box to appear when I check the box next to "I paid more mortgage...." but nothing happened. Where can I enter my total interest amount? Picture attached.

Deductions & credits

If you click on the blue Learn More link by "The interest amount I entered here is different from what's reported on my 1098" it refers to the fact that you enter the different amount for the Qualified lender in the Interest Paid box.  (See the screenshot below)

Checking the box will cause the following page titled "Explain Your Difference".
