How can I replace my Shopify URL with my new domain on Google search?

[mgraham_1212]

i recently brought a domain though when I search on google my shopify url still comes up along with it instead of just the domain. How can I fix this this? I have tried on settings but still same thing is happening. I will send a screen shot in..you can see my shopify site 44d... (blitzbeautyspaandmassage.co.uk)

Many thanks
