Why am I getting the rebate credit from the stimulus even though I already told them I received them already? How do I go about fixing this?

I filed already and upon looking at the downloaded pdf, it says that I'm getting the rebate credit, but I checked the box saying that I already got my stimulus checks. Should I amend and see what's going on? Or can I talk to someone from Intuit and find that out? I don't want the IRS down my back..
