How do I copy and paste text from a Note

It works the same way copying and pasting text in any other application on your PC works. Highlight the text you want to copy, press Control- C. Go to wherever you want to paste it, position your curson and press Control-P.

I see what you're saying. I always use Control - C so I'd never noticed.

You screenshot would indicate that you are attempting to “copy” an image of some sort, not selected text. If this is the case, try your usual procedure with a different text selection.
