Something happened to me. IRS deducted 1400 from my tax refund. why do they do that?


That usually means you indicated that you did NOT receive the 3rd stimulus payment.  So on your tax return there was entered $1,400 as a Recovery Rebate Credit on Line 30.

The IRS has records showing you were sent the 3rd stimulus payment so they removed the credit from your tax return thereby reducing your federal tax refund by $1,400.
