How do I make sidebar display on right of Q&A Content

Hi. I've installed the Q&A plugin and selected Left align in the Settings BUT the sidebar is appearing beneath the Q&A content instead of to the right of it. Please could you take a look and let me know if there's any CSS I could insert that would help!

Here's a page where you'll see the problem:

There is ALSO a 'p' that appears above the 'submit' button. Please could you let me know why that's there and how to remove it.

Thank you!
