When the IRS makes the correction on an already filed and accepted return then the extra refund will either be added to the refund you have not yet gotten or sent separately. Expect a letter from the IRS explaining the difference.
If you had a balance due on the original return :
And you have NOT paid it yet then you only need to pay the adjusted balance due by 5/17/21.
But if you HAVE paid the original balance due then the IRS will send you the difference in the bottom line back.
Either way do NOT NOT NOT mail in an amended return ... the IRS will correct this issue automatically.
