They should have one. Might have to pay depending on what is wrong with the old one.
They are likely to replace it if it broke off in the phone or not working due to normal wear and tear. If however you lost it and phone is no longer in warranty they will be best to give you all options available.
They should be able to help you find one.
They should as they repair Samsung devices. My s pen broke off in my note 8, took about an hour for the to take my phone apart to remove the s pen and put phone back together. They also gave me a new s pen...
If they find have it, they can advise where to get it
I might have 2 look when I get home
