How do I download iTunes for Mac OS Big Sur

According to Where’s my iTunes content on my Mac? - Apple Support:

"In macOS 10.14 and earlier, iTunes was the app where all your media lived—music, home videos, TV shows, movies, podcasts, and audiobooks. iTunes was the one app for everything, including backing up and syncing your iPhone, iPad, or iPod.

In macOS Catalina and macOS Big Sur, your Mac has three dedicated apps—Apple Music, Apple TV, and Apple Podcasts. Content from your iTunes library has migrated into each of these apps so that you don’t miss a beat. To back up, restore, and sync your content, simply connect your device to your Mac and use the Finder. Or, just sign in with the same Apple ID on all your devices to sync content seamlessly."

Apple split iTunes up in Catalina. Use the new applications instead.
