Please share your site url.
So that I can check and let you know the exact solution for this.
Please share link which you want to remove price and 'in stock' wording from Google listings page
I've attached two examples and the links to those are:
https://www.bowierae.com/products/the-bec-special-edition (includes price in metadata)
https://www.bowierae.com/collections/dresses (includes price in meta description)
Thank you again
