Misreported how much Economic Impact I received

[Jain06]

I filed my 2021 federal returns, and reported that I received $2,000 in Economic Impact.  However, I just learned via my Letter 6475 from the IRS, that I only received $1,400 in 2021, and that the extra $600 was part of the 2020 stimulus.  Because I was able to file Head of Household, they still owe me $1,400 for 2021, not the $800 I thought.  How do I file an amendment to get back the additional $600 I paid.  I don't see in option for this in the Turbo Tax amend return online portal.  I don't even see a section for it on the IRS 1040-X paper form.  I don't believe they'll just decide to send it back to me without me asking...  Thanks!

Form 1040-X will be ready after tomorrow. Just one day away before you can amend your tax return. You should wait for the IRS to finish processing your return firm. IRS might make the adjustment for you.
