3rd stimulus payment deducted from my 2021 refund

I am filing "Married, filing jointly".  My 2020 and 2021 AGI is less than $150,000.  I received a notice from IRS that my return has been approved, but they are deducting $2,800 for the 3rd stimulus check I received.  I have W-2 income of over $150,000, but my husband's business showed a loss for 2021, which reduced our AGI to less than $150,000.  Is there a different way to calculate AGI for purposes of the stimulus income limits?
