What is JotForm?

At JotForm, we want to make sure that you’re getting the online form builder help that you need. Our friendly customer support team is available 24/7.
We believe that if one user has a question, there could be more users who may have the same question. This is why many of our support forum threads are public and available to be searched and viewed.

My understanding is that you want to clone an existing form. If that is correct, then you can easily do that in the My Forms page.
Just select the form and then click the "More" button. After that, choose the "Clone Form" option.
You can also clone form based on the URL, here's a guide: https://www.jotform.com/help/42-How-to-Clone-an-Existing-Form-from-a-URL.
Hope that helps. Thank you.
