Need to forward email from att.net to a new email address

You aren't allowed to forward mail that comes into Yahoo to another email address unless you pay for Yahoo Mail+.  😟

So I've just paid for the privilege of having my mail forwarded (shame on Yahoo...), but am still not understanding how to forward the mail that comes to that address to the other mail server I use.  Note - the address that I want to forward emails from to the other server is listed as my reply only address.  Leary of changing that since the warning says that everything associated will be deleted permanently.

There should just be a Forwarding section in Settings/More Settings.  Yahoo does say in the fine print that  The forwarding address can't be one of your recovery email addresses.

Is that reply only address also your recovery address?
