Can you brine a jennie-o premium basted turkey?

Needed to know myself; and here's what I found:

Q: What are self-basting turkeys?

A: Some turkeys are sold as "basted" or "self-basted". That means that a solution, usually containing natural broth, stock, or water, and seasoning has been added. The percentage of solution added to the turkey is printed on the label.

So you could, but it is alreadybasted.

Good luck and happy holidays!
