If Check for Updates isn't an option in the Help menu, then you downloaded iTunes from the Microsoft Store.
Looking for iTunes on your Mac?
The iTunes app is no longer available on Mac. The contents of your iTunes media library are organized into their own dedicated apps that are installed with macOS. You can access your music in the Apple Music app, movies, TV shows, and videos in the Apple TV app, podcasts in the Apple Podcasts app, and audiobooks in the Apple Books app.
