Recovery Rebate - Newborn

Hello,

 

I filed my 2021 tax return already but it didn’t calculate the recovery rebate for my new born child of $1,400. At first, I thought the IRS will calculate it and send it separately but I just read online I have to claim it on my tax return. FYI. Turbo Tax did not mention or ask to input the additional recovery rebate credit for new born but only ask how much I received thus far for the recovery rebate credit and to input what I received. 

Please advise.
