Savings bonds

Hi, I’m new to navy federal and saw online that they redeem treasury bonds. Do they still offer this? Most places don’t. Is there a limit to how much I as a new customer can redeem? Do I need to bring anything ID other than a driver’s license? Does the cash get deposited directly into my Navy Federal account?

Also when I created the account it said I would need to submit proof I was eligible for an account through a family member, but then it never gave me the chance to. Will I need to bring that proof when I go in the bank?
