intake form issue

I have been using Squarespace and Acuity for years now. The one issue I keep having is when I book an initial appointment FOR a client, they tell me they have filled out the form that I have attached to the initial appointment- and I can't find it. They obviously see the link in their confirmation email. Where does that form go? 

If they book the appointment- no problem, the form comes through in the reminder emails, and is also on the calendar ics and is visible on Acuity. 

I just put myself as a client to see what would happen- but again, I can't find the form. I do receive a filled out form if I click on "send to myself" at the bottom. 

So there is a workaround- I can ask the client to send it to themself, then forward it to me. But I shouldn't have to do that.

Where can I find a filled out form? 

thanks
