unlink verizon email from yahoo

Iwant to sign up for the domain service so I don't lose my verizon.net email when I move (no Verizon service there.)

The domain service says that I have to unlink from Yahoo first.  Then it points me to 'Profile/online experience/change my online experience.  I have looked and that option doesn't exist anywhere under accounts and services.

I want to save my email and contacts before I unlink, so I think I need to do it this way.

Any help would be appreciated.

(BTW-I know there are other posts on this, but none show the solution.)
