WP Dashboard access is incorrect https://prnt.sc/yrk734
Free version of the Elementor does not have the option to edit the shop page. Only Elementor Pro allows you to create templates for the shop archive pages.
All the theme settings to edit shop page layout you can find in Theme Options > WooCommerce > Shop, Shop elements.
Also, you can edit only product description using Elementor. To be able to do this you need to enable Elementor for the products in the Elementor settings https://prnt.sc/yrk9cn
