new domain not connected to new website

Hello-

I purchased a new domain - www.risajohnsonphoto.com - and I then designed a website that I would like to publish and take live, but they don't seem to be connected- the website seems to have the random URL accordion-garlic-3crd.squarespace.com and the website shown under my domain looks like the template I started with and seems to have a trial expiration date- I paid for a full website subscription, why is it not under my domain?

Thank you for any advice....
