free 1 year trial of Apple TV

I bought our computers on 03/22/2021 and I read that we have 3 months to claim our free 1 year trial of Apple TV. When I try to sign up for it, it only says that we have a 7 day trial. I haven't committed to that because we should be able to get a year. Do I just sign up for the 7 day trial and it will automatically sign me up for the 1 yr free trial?
