Filed Recovery Rebate Credit ,and then received my $600 stimulus check days later after checking IRS site which said to file for the rebate based on my SSN

Hi all, I filed my Recovery Rebate Credit ,and then received my $600 stimulus check days later after checking IRS site which said to file for the rebate based on my SSN based on their tool online. 

 

How do I go about this process now? I basically was given two $600 stimulus checks. Would this need to be amended in my 1040X form, or is there something else I would need to do? Not sure how I could "uncheck" the recovery rebate credit since my taxes were done through TurboTax Online.

 

Anything helps! Thanks!
