Income Summary page does not reflect the amounts I entered from 1099-DIV

I just started a new 2025 return.  I have entered information from only one document thus far -- a single 1099-DIV- lines 1a and 1b.  When I go to the Income Summary page the amount showing there in the 2025 column is rather different from either of the amounts I entered and it is not equal to the sum of them either.  When I click on the amount showing on the Summary page, a pop-up Amount Description box appears and it shows the amount I entered from line 1a only.  

This is the only data I have entered in this form so it is not pulling info from some other 1099-DIV or anywhere else.   What is going on?
