@kjnoire - first, lesson learned for the futur: wait to amend until the IRS processes the original return. (in this case they would have made the adjustment automatically)
2) wait for the amendment to complete processing. You can see progress here:

3) in essence, once the amendment has cleared, you have not received the Recovery Rebate Credit and you need to declare it. So it's going to take another amendment, checking the 'other' box and notating "RRC" and $1400 due to you. But wait until that first amendment is completely processed so you know what the IRS actually did and can act according
