Turbox Tax Only Showing $200 in Additional Child Tax Credits

Here is one I do not understand and could use some help on:

 

My wife and I each have a letter from the IRS showing we each received $900 in 2021 Advanced Child Tax Credits ($1,800 total). 

 

When i go through the Deductions & Credits section of Turbotax and input this information, my calculation sheet only shows an Additional Child Tax Credit of $200. 

 

What i don't understand is why my Additional Child Tax Credit is not $1,800 ( = $3,600 - $1,800 in Advanced Payments). 

 

Can anyone help explain this? My daughter was born in 2019 if that helps.
