I have a client that only received 832 for the first EIC payment because they used the 2018 return (we had not filed 2019 yet).  However, she only had 5800 AGI in 2020.  We put in for the other 368 using the Recovery Rebate Credit worksheet.  I filed the return; it was accepted.  But now when I open the return, it says the IRS made a change to the return after it was filed.  further viewing shows the 368 adjustment was denied.  Now what do I do (or what should the client do)?
