Hi CKhime,
It sounds like you have an Apple ID that is in the account recovery process. If you missed the window you may need to start the process over. Once you do, you'll want to follow the steps below found in the article here: How to use account recovery when you can’t reset your Apple ID password
"After you start account recovery
After you request account recovery, you get an email with a confirmation of your request and the date and time of when you can expect to regain access. This email arrives within 72 hours.
- If you submitted your account recovery request with iforgot.apple.com through your device's browser, you should avoid using that device during this period. Using that device might cancel account recovery.
- To avoid delays, turn off other devices that are signed in with your Apple ID until account recovery is complete.
When the wait period is over, Apple sends you a text or automated phone call with instructions to regain access to your account. Follow the instructions to regain access to your Apple ID.
In some cases, you might be able to speed up the account recovery process or reset your password immediately by verifying a six-digit code sent to your primary email address. You might also be able to shorten the wait time by providing credit-card details to confirm your identity. If you’re given this option, an authorization request goes to the card issuer.*"
There are also steps for checking the status or canceling the request in the same article if needed. Be sure to check your mailbox and spam folders on the date provided in your initial email so you don't miss the window to recover.
Cheers.
