This is a guess.....but $1400 sounds like the 3rd EIP payment. Check your account online with the IRS. Does the IRS show that they sent you $1400 for the 3rd stimulus check? Was there $1400 on line 30 of your tax return? You cannot get the $1400 twice.

If you really did not receive the $1400 and the IRS says you did, then you can have it traced.
