How much is on line 28? Anything? And line 30. If your income is too high the Child Tax Credit and Recovery Rebate Credit will be phased out. I can't think of anything else. Unless the IRS increased your income and made you ineligible for the credits.
Or maybe you tried to claim the 3rd Stimulus payment for you and your spouse again on line 30? Line 30 should be only the 1,400 for the baby.
