@naveenrkumar - normally the issue with an adjustment on the Recovery Rebate is that what you told TT you received for the 3rd stimulus does not match the IRS records of what they sent you. It's not the result of a caculation error by TT, it's the result of what you entered vs. what the IRS records indicate.
you are eligible for the stimulus or the Recovery Rebate credit but not both!
best to check your bank account records from March - May, 2021 to see if you actually received the stimulus.
