Question Regarding Stimulus Rebate Credit

I had a child born in 2020 and claimed the missed stimulus payments on our 2020 return totaling $1,100. It's unclear to me with what's supposed to happen here. From what I have read it's a refundable tax credit. Our tax account currently reflects a $1,100 account credit. No refund issues though. Does this mean they will be sending a check for $1,100 as one of these plus up payments or would this just be a credit on our account? Any help would be appreciated.
