apple music subscription question

Hi,

I subscribed to the trial for the first month as a student. According to the terms of the event, if the subscription is renewed in the second month, I can get the Bluetooth headphone of beats. But I'm not sure what my shipping address is, I guess it may be the address in "country/Region" in my account, but I can't confirm whether my current address is correct, please let me know how can I check or change it.

Thanks
