Changing name and domain host

Hello,

I want to rename my website, got a new www, plus moved my old www to a new host to have them all in one place "squarespace"  So both www will be hosted by squarespace now, I tried to point the new domain with the CNS you provided following the step 1, however they need other information that I don't have, can you please help me? Homestead will still host the website. [can add the image says error, it's a jpg but doesn't accept it]

"Host", "type" (CNAME, etc) , "Alias data" are the only 3 fields I get.

Thanks
