Unresponsive after hitting Cntr-Z

At the last step of Mario Tutorial, I hit “Cntr-Z” by accident and that seemed to take me out of PostgreSQL. How can I get back on to complete the tutorial? As you can see, I get “codeally@f66e26c7af93:~/project$” in the terminal. Thank you.

You can find the instructions in the coderoad history.
Scroll up and find a menu icon in the top left corner of the coderoad tab. Click that and you should find an option to “review”.
And this will show everything you have done so far so just find the instructions for running psql.
