I just pasted it at the very top of my style.css and it worked.
php code doesn't normally belong in a style sheet, and that is not a correct solution. Think about it for a minute. If you were creating a site in just HTML, would you find or place the path to the style sheet inside of the style sheet?
Can you please tell me what need to be inside my /wp-content/themes/Distinct/
I'm afraid I can't. You created the theme. You can create sub-folders if you like, just as long as your files properly reference the path to any assets located in those folders. Clearly you are going to do this your own way the first time rather than take a breather and pay attention to advice or any published learning materials, but I do admire your focus. Carry on, soldier!
Good luck and best wishes!!
