I cannot find my forms in my account

I had more forms saved but now only 1 appears...

I have checked your account and see that there is only one form in the account. You may have created the form by not logging into your account, in which it is created in a guest account. Please provide us with the form ID/URL that is created, so that we'll try to locate the form and assist you further.

Thanks!

Precisely the problem is that I found only one form. Always I create the forms logging in my account, indeed the form I'm searching was used, below you can find the link that I used...

I didn't found the ID, only this URL. Thank you.

That form has been deleted. You have probably accidentally deleted. I cannot find it in your Trash anymore so you have probably deleted it a long time ago.
