There must be a card attached to your Apple Account.
Check Settings, [your name], Payments & Shipping
If in doubt you can reach out to Apple Support directly. You should be able to reach them here
Contact - Official Apple Support
or phone numbers
Contact Apple for support and service - Apple Support
If there is no card attached then attach one as soon as possible, life will be much easier with one.
