Why do I not get Child tax credit for my newborn (Born in Auguat 2020) ?

A child born (even on Dec 31) is considered to live with you the whole year.  So pick the Whole Year at the top of the drop down box.  Go back through My Info and check.

Should I go ahead and amend the tax return ?

Yes if you already filed then you need to amend it.  If you haven't filed yet or it rejected you can just fix it.
