What am I doing wrong? This does not work --Reset NVRAM Shut down your Mac, then turn it on and immediately press and hold these four keys together: Option, Command, P, and R. Release the keys after about 20 seconds. This clears user settings from memory

What about it doesn’t work? Zapping the PRAM clears certain settings, not your data. The easiest way to remove all your data and settings is to reinstall the OS.
If you’re getting rid of the computer, there are other steps to consider:

Did you set a firmware password? That disables PRAM zapping. Boot into recovery mode (Command-R during startup) and turn it off.

Yes, that’s the startup in recovery mode, which is different than a PRAM zap (which just clears the settings in NVRAM then boots normally). Of course, you can access disk utility in the Utilities folder if you need to.
That’s normal for a NVRAM/PRAM reset, repeated chime (or Apple logo) then a normal boot.
Thank you for your answer.
After I conduct that step, it doesn't shut down or go into macOS Recovery mode. While holding down the keys, I get the startup chimes a few times during the 20 seconds. Am I wrong to expect that it would go into recovery? I do not see Disk Utility from the Utilities window --it goes to the usual login icon.
Thank you for this answer. Am I supposed to log-in again? Because when I do things look as they usually do and there is no sign of
