Thanks, @rogge1722. Your answer worked for me, after one additional discovery, and modifying original 1099-DIV info as @peters1050 mentioned.
I needed to enter foreign tax from six countries, but couldn't figure out how to specify more than four.
On the "Where Did You Receive Dividend Income From?" screen, there are only four dropboxes in the "Country" box, and no obvious way to enter more than those. However, almost by accident, I found that if you hover within the "Country" box (outlining the four droplist) and use the scroll wheel on your mouse, it will scroll up, revealing more blank ("not applicable") droplists, which you can then use to enter additional countries.
Also, on the 2019 1099-DIVs, Foreign Tax Paid is now Box 7.
