Where can I find the criteria that the IRS uses to base the taking or not at?


Go to your IRS tax account - https://www.irs.gov/payments/your-online-account

If your account shows that you received the 3rd stimulus payment of $1,400 then that is why the IRS removed the Recovery Rebate Credit of $1,400 because you already received the stimulus.
