Password not working iMac

Which password, are you referring to your Administrator password or your AppleID? Your question is not complete so we need to ask. If it's your Administrator's password please do the following:

1. Restart the Mac while holding down the Option key, and double-click the icon for the Recovery partition. ... 
2. Choose Utilities > Terminal.
3. In Terminal, type resetpassword .

I just loaded Catalina on my computer and now my Macbook Pro does not recognize my password when I try to unlock my computer. Please advise what I need to do next. I have gone through the Recovery mode and typed "resetpassword" in the Terminal Window but no options popped up once other than exit when that screen was on.
