I’m been try to get my old iCloud account but I can get it

Did you already setup the device? If you did, then there’s no getting to your iCloud account as the device is already setup with your Apple ID and password, or were you not able to setup the device using your Apple ID and password?

Is this an old Apple ID? Did you forget the ID and password?

So you cannot get beyond #6 - Set up your iPhone, iPad, or iPod touch - Apple Support?

Then -

If you forgot your Apple ID - Apple Support

If you forgot your Apple ID password - Apple Support
