I sent a payment of $300 with my 2020 Return. Now, TTax says I will get a $1200 refund due to CARES ACT . Do I get the $300 back too? How? The Amned return says nothing.

Turbo Tax's Amended Return makes no mention of the money I already sent in as directed in the initial return I sent in. Does the refund it now reports include the money I already sent in? How do I get that money back?
