I have a question about my domain name.

I am trying to understand if I own the domain name I purchased because I haven't actually published my website.

I was going to design this by myself but found someone to design for me through Word Press.

Because I couldn't figure out how to access the website domain name I purchased through Intuit, I purchased another domain name through GoDaddy at my web designer's request. The one purchased through GoDaddy is up and running but I would prefer the one I requested through Intuit. I'm unclear as to how to make this my website address. I'm very technologically challenged...

Can anyone help?
