Gmail Account Recovery Assistance

I need your expertise to regain access to an old Gmail account whose address I still remember but whose password I have forgotten. I have the linked number but google send otp to recovery mail and I mistakenly put recovery mail same male that I want to recover
And I have no longer have access to any recovery email, or other fallback options tied to the account, so the standard Google Account Recovery prompts are not getting me through.

What I’m expecting from you:
• A clear, methodical plan to work through Google’s recovery tools and any alternative verification routes that comply with Google’s policies.
• Hands-on guidance—screen-by-screen if needed—until the account is successfully unlocked and I can sign in again.
• A short, plain-language checklist I can keep for future reference so I don’t get locked out again (backup codes, updated recovery methods, 2-Step Verification setup, etc.).

Please share any similar Gmail or Google Workspace recovery successes you’ve handled so I know we’re on the right track.
