Where is the user account/profile?

Hello,
I’ve been happily using Scrivener on my Mac for several months, but only just realized I don’t know where to find my account/profile. I discovered the need when I started a script project, and my email address was autofilled - but it was an old email address that I’ve not used in many years. I’d like to update the address, but I can’t find where to do so. FWIW, my Scrivener license was purchased with my current email address, which makes it especially strange that the script would autofill an old one.

Thanks for any help you might offer!
Lisa
