Game crashed, lost account

I wasnt logged into my Game Center account when app crashed and everything was gone. So… don’t know what i should do now. Transfer request is submitted but don’t know which —> log-in method i should choose so the support keys doesn’t change and I don’t create a new account and key… Guest? Game Center?
Or will it just open like normal when transfer is successfully done without asking me how I wanna log in?! Thank you for your help.
