Hello there, @drwhite ...
If you are wondering about how to make your "Announcements" course navigation button visible in your course, you can follow the instructions outlined in this Guide: How do I manage Course Navigation links?.
You can also display some of your announcements at the top of your course "Home" page if you want. Here's how to do that: How do I show recent announcements in the Course Home Page?.
I hope these Guides will be of help to you, Marli. Sing out if you have any other questions about this. Stay safe...be well.
