How can I see what has been sent to people? As in the replay e-mail address?

I am not exactly sure if I understood your question correctly. 

When a form is submitted an Autoresponder email will be sent to your users if you created an Autoresponder email. 

You have only one form on your account and that form has an Autoresponder email. However, your Autoresponder email is not set correctly. 

You did not select the Recipient Email inside of the Autoresponder email settings.

You should select the email field of your form as the Recipient Email. 

More about email Notification and Autoresponder settings, you can find here:

You can also check the email logs on your account to see what was sent.
