Where is the 2021 Recovery Rebate Credit calculated?

Looking at records online, I see an amount of $1400 is payable.  With that, I see I only got $2800. Which means I could be missing $1400.

 

I printed out the tax forms from using TurboTax Online, and looking through them, I am not seeing that $1400 credit, or a worksheet to even calculate the credit.  I do recall answering a question about the amount of credit received, but just not seeing it in the paperwork here.

 

In addition, I am online now looking to make changes to 2021 taxes, and even there I am not seeing anything related.

 

Look on the IRS web site, I am seeing a mention of a 2021 Recovery Rebate Credit Worksheet which I cannot even find anywhere. 

 

Thanks!
