Thank you @derricksrandomviews. Your site is great and that helped.
I also reached out to customer support and they this is what they told me to do (which I did with my other domains and it did work out):
"I understand that you'd like for your domains to point to other pages within your Squarespace site. I'd be happy to assist.
"You can forward your domains to a specific page. You'll follow the same process as forwarding a domain to a non-Squarespace site but you'll need to enter the full page URL, including the specific page slug.
"I'm linking the instructions and guides for this process:
Forward to a non-Squarespace site
Forward to a specific page "
Open DNS settings for the domain you’d like to forward.
Delete the Squarespace defaults section. Your domain can’t forward to another site when these defaults are in place.
From the ADD PRESET drop-down menu, select Forward domain.
In the pop-up message, enter the full URL of the specific page to forward to, and then click Add. This creates a Forward domain section with an A record and a CNAME.
Check your work by opening an incognito window
