Hi, at this time there isn't much of an integration between Elementor and Forms. You can use the drag-and-drop editor provided by Forms to arrange your text and inputs in a Form, then insert that Form in an Elementor design using a Toolset Form Element block, but the Form builder is not integrated with the Elementor builder. The input fields must be arranged using the Toolset Forms builder. There is an advanced mode that allows shortcode-style development, or a drag-and-drop editor experience.
Are there plans for more integration with Elementor?
So many other plugins are doing so, and Toolset is being overtaken. I'm disappointed by this as I've been invested in toolset for a long time, and I like what it does. But it seems to be standing still.
No plans that I'm aware of. We're focusing on the Block Editor integration instead of compatibility with every new page builder that comes out, so I don't expect to support any more integration with Elementor, WP Bakery, Divi, or Beaver Builder.
