JotForm is a free online form builder which helps you create online forms without writing a single line of code. No sign-up required.
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. If you’d like help immediately, feel free to search for a similar question, or submit your question or concern.
Are you trying to restore a deleted form? If so, please follow the steps from this guide: https://www.jotform.com/help/134-How-to-Restore-Deleted-Forms. But I can see that you are a sub-user account, you can ask the main account holder to restore the form on your behalf.
If you are asking on how to locate a deleted submissions, unfortunately, it's not possible. We don't keep a backup of the deleted submissions so I'm sorry to say that those submissions are unrecoverable.
