If you got the full payment then nothing should be on line 30 of the form 1040 so you have nothing to correct ... look at that line first.
If you file with the wrong information then the IRS will automatically correct the situation. But if you went thru that section already then you if you are still eligible for the RRC you should be able to review that section again ... follow the prior instructions or switch to the FORMS mode if you are using the downloaded version.
