Reset password iforgot email

I have discovered I have a second apple ID.

I requested password reset by email and have waited for 2 days. Does Apple send email to rescue email, or to apple ID email? As I have discontinued rescue email when setting up new ID.

I thought the last time it took quite a while, but thought they sent it to ID email.

I need to know so as I can call them if that is the case. Just don't want to be on hold for over 3 hours like the last time I called.
