Trying to set up Firefox Sync and it says my email address is already in use, but won't let me sign in.

I'm trying to Sync Firefox between my new Android phone with my Macbook Air. It tells me I need to create an account, but says my email address is already in use. So I try to put in the codes in the three boxes, and it leads me back to set up a new account. How can I reset this? How do I proceed?

Thank you for your help!
