Normally the child theme initially has only the functions.php and style.css files. You add and create every other file. So if a folder is not already present in it, you have to create it! Just make sure to keep the same file path in child theme as it is in parent theme!
So if in parent you have this path: june/woocommerce/single-product/related.php
The same will be in child theme: june-child/woocommerce/single-product/related.php
