You and your spouse would be eligible for $1,400 each from the stimulus payment if you both were U.S. citizens with valid social security numbers and neither of you was claimed as a dependent on someone else's return. You also would not get the full amount if your combined income was above $150,000.
If it does not sound like any of the requirements would affect you or reduce your stimulus payment, an amount may have been inadvertently entered on your return. If you review your Form 1040, the amount of stimulus you are receiving will be on Line 30 Recovery rebate credit.
If that amount is incorrect, you can look at the Recovery Rebate Credit Worksheet to determine the source of the error. Line 12 should be $2,800 for your situation and Line 13 should be $0. If Line 12 is incorrect, that means either you or your spouse did not have valid social security numbers. If either of you has an ITIN that begins with a 9, that person would not be eligible for the third stimulus payment.
If Line 13 is incorrect, that means you entered that you already received some amount for your stimulus back when they issued the payments in March through May of 2021. If you did receive any stimulus, the IRS should have sent you Letter 6475 which says the amount of payment you received.
If the amount of stimulus you claim to have received does not match the IRS's records, then they may automatically adjust your refund to match their records. In that case, no amended return would be necessary.
