Today I updated my main Windows 10 Version 1909 laptop (KB4537572, KB4551762, & KB4540673) and afterward saw the "Windows Update Attention Needed" message on the first Settings screen. Even though my system had checked for updates this morning and had just applied updates, I clicked on "Check for updates" on the Windows Update page.
That solved the issue for me.
Apparently that is just a new warning Microsoft added to let you know your system may be out of date. Either it's pretty fussy about how long out of date or perhaps the feature was just added and Check for Updates needed to be run once to populate a new last updated indicator (instead of looking at the date/time of the indicator already there).
