Error with website

I recently searched up how to change my domain name, and I did a the steps given from this website : https://www.godaddy.com/help/changing-your-wordpress-domain-name-6495

I changed it, but might’ve changed it to a domain name with a name that’s already taken.

When I try to go to my website, it keeps redirecting me to the domain name I changed it to, “filmblogs.com”

my original domain name is, “cupidmiracles.com”

Can I get a reset on my wordpress or something ?

Thank You !
