Account recovery is a two phase process once started. Phase 1 is the evaluation period, usually 24-48 hours but can be longer or shorter. This phase says Apple is evaluating your info and you’ll get an update after the posted time is over (people mistakenly think it means they’ll be able to reset the password immediately after this first phase.)
Once phase 1 is done it enters phase 2 where https://iforgot.apple.com/ will give you the final number of days (can be weeks) you’ll wait. On that final day you’ll get a text, follow that text immediately.
