Hi, So for year 2020 i claimed my 2 sons. I received 4200 for recovery which is correct. I have a 3rd son that was not claimed thinking that his father would claim him, neither of us received recovery rebate for him. This year 1 of my oldest son will file by himself. Now what I want to do is claim my 3rd son to get 3rd stimulus for him. I will be back to 2 dependents. How can I claim this recovery rebate credit if on my letter shows 4200 which is correct for 3 stimulus payments? do I enter 2,800? To get that credit for my son? I'm very confused on what to do!
