My "second" stimulus amount was not correct:
I filed my 2019 return using an incorrect 1099, which made me eligible for a lower stimulus payment. When I received a corrected 1099, I amended, but I had already received a lower amount of stimulus. I should have been eligible for more.
The standard answer is that I can just claim the difference under the Recovery Rebate Credit in 2020. However, this is based on 2020 income, under which I am not eligible for any payment.
Is there any way to get this corrected? I feel like I did nothing "wrong" except rely on my broker statements and file my return timely. And now I'm $300 short. The timing of filing or amending shouldn't affect the eligibility for credits in this way.
