Im trying to reset my password thru the Terminal and I get this screen

There are no volumes and no available users. Erase the Mac and reinstall macOS: Erase and reinstall macOS - Apple Support.

For future reference, don't use Terminal to reset a password. To change the password of a Mac User Account, refer to Change the login password on Mac - Apple Support. If you forgot that password, refer to If you forgot your Mac login password - Apple Support.

The following may be relevant: If you see an 'Unable to sign you in to your Apple ID' message - Apple Support.

In brief, you should give things a rest for 24 hours before trying again. If you tried repeatedly to log in and it failed (for whatever reason) you won't be able to use Account Recovery for at least that long.

Besides, I do not know what using Terminal might have done to complicate things.

Do you not have a Time Machine backup?
