DNS mapping support for a new SquareSpace website on a Google Domain migrated to SquareSpace.

I decided to unpublish my old garbage Google Sites website.  Obviously, Squarespace's design aesthetic is orders of magnitude more pleasing.  

Anyway, I wiped out my DNS records and then requested that Squarespace leverage the default settings.  I have my domain pointing to my https://vuvuzela-calliope-jxpl.squarespace.com/ site.  24-72 hours?  I hope so.  My site offers appointment booking (HIPAA-compliant) so hoping it's quicker than that.  

I'm struggling with the help pages to find what I need and it appears there are videos but my browser seems to hide them (even with AdBlock off).  

I'm keeping my MX for my Google Workspace mail.  and the CNAME is already pointing to verify.squarespace.com

I have a bunch of TXT records that take care of inbound spam and my encryption for compliant email.  

I'm really not sure what else I'm missing.  Help?  TYVM.
