Updating an iPhone:

Update Using a Computer:

Have a Computer Handy? If so, try using a computer to update. Go here: Update your iPhone Using a Computer - User Tip. If any updates are available, they will install, sure enough.

Unfortunately, the iPhone 5S is not compatible with iOS 13 or higher.

That model can be updated to iOS 12.5.7, no further.
