So how do I update from computer please

From: Update your iPhone, iPad, or iPod touch - Apple Support

If you can't see the update on your device, use your computer to update your device manually. Learn how to update your device manually if you're using a Mac with macOS Catalina or later, or if you're using a Mac with macOS Mojave or earlier or a Windows PC.

Follow those links, depending on what computer you have.
