Hi Nikkihawkins05

Re: "the voiceover commands won’t turn off and it won’t let me login to my computer"
Apple support's online article (link below) :
Turn VoiceOver on or off on Mac - Apple Support
says:
✽ Press Command-F5. (If VoiceOver is on, pressing the keys turns it off.)
or
✽ Use Siri: “Turn VoiceOver off”
or
✽ if your Mac has Touch ID:
press and hold the Command key while you quickly press Touch ID three times.
