Ash here from the Shopify team. Welcome to the Shopify Community!
I'm happy to help out with your question! Just to ensure I understand the end goal correctly, are you looking to move your quantity selector, add to cart button, and accelerated checkout button all below your product description? If that is correct, please let me know the following:
Once I hear back, I'll have a better idea of how we should proceed. If I didn't quite understand correctly, please feel free to clarify in your reply here. Looking forward to hearing from you!
Understood. Thank you for getting back to me with clarification on this request. I'd like to move our conversation to email so that I can authenticate you on the shop in question and loop our theme support team in on this request. I've just sent an email to the email address on file with your Shopify Community account. Please reply to that email and include your .myshopify.com URL in your reply. Also, if you use an alternate email address to log into your Shopify account, please note that in your email reply as well so that we can authenticate accordingly.
Looking forward to hearing back via email and continuing to assist!
Thank you for providing your URL. However, I do need to hear back from you via email before I'm able to take a closer look into the back-end of your account. Were you able to find the email I sent out the other day? If so, please reply directly to that email to complete authentication. If you're unable to find it, please let me know here and I can try to re-send it.
