Retrieve a deleted form submission

I accidentally deleted a form that was submitted. Is there a way to get this back? 

If you are referring to a deleted form submission, unfortunately, it is not possible to retrieve the deleted submission. However, you may access the information from the notification email received. If you have integrated DropBox/Google Drive to the form before the form submission is received, you may also get the information from the respective cloud storage.

If you are referring to the form itself, you can find the deleted form in the Trash folder. You can restore it from the Trash folder if it is not purged. 

Hope this information helps!
