Hi there and welcome
You mean you are trying to create a new Google Account? And the email address has your email address there with a 1 next to it?
I can connect to your computer if you wish and check and solve this directly and have made a request to do so.
Please accept it
ok, I only offered it as you requested additional service.
If it was when your trying to log in, it is just detecting a previous sign in attempt on this computer.
Remove it and add your details.
Does it let you sign in?
