Hey there, JBarchart. You've come to the right place, the Community is here to help.
 

The Paycheck Protection Program banner you're seeing is to help businesses who may want to submit an application to potentially receive relief funds for their operations. If it's displaying in the form of a pop-up window when you open your homepage, you could try disabling these types of notifications in your preferences. I'll show you how:
1. In the menu bar at the top, go to Edit, then Preferences.2. A window will display with a scrolling navigation bar on the left side. Choose General from the list of options.
3. Open the My Preferences tab and select the Turn off pop-up messages for products and services box.4. Hit OK to complete your changes.
 

Now unwanted windows won't display when you open your books.
 

Here's a helpful resource which provides further information about changing settings in QuickBooks: How to change preferences in QBDT
