MOS Catalina update

In fact, your MacBook Pro 2019 can run the newest, latest release of macOS 14 Sonoma.

➡️ macOS 14 Sonoma is compatible with the Macs listed here

However, I would advise that you hold off upgrading to Sonoma because it is so newly released.

Instead, if you intend to upgrade, I suggest you go to macOS 13 Ventura. It has been out for a year and has received feedback and several point update improvements.

❗️ Do NOT upgrade

…until you have made a Time Machine or other backup of your startup drive.

The fact that you are actively using Time Machine puts you ahead of the curve for this upgrade.

I'm sure you'll do fine when you finally feel comfortable enough to take action.

Good luck! 🍀
