Deleted Widget Entries, but strange redirect still occurs?

I started to notice after using Widget Entries for a bit that the home page of my site began redirecting to a widget I created called “testing”. In other words, upon going to https://www.example.com/, WordPress would redirect to https://www.example.com/widget/testing/

Why does this happen? Why does this behavior continue even when I’ve deleted all the widgets I created, then deactivated and deleted the plugin? Where do I look to remove this redirect? .htaccess doesn’t have anything in it related to this that I can see.

Please help me with this. It’s delaying my site being able to launch.
