If you get a message about not having 'sufficient information', you will not be able to reset your security questions. Realize that several years ago Apple transitioned to using to two factor authentication instead of security questions and has been encouraging users to switch to the newer security system. Your next recourse will be try to change to two factor authentication as outlined in this article --> Two-factor authentication for Apple ID - Apple Support Follow the instructions in the section "Turn on two-factor authentication for your Apple ID"

"If you’ve forgotten your security questions, there isn’t a way for Apple to reset them for you, or another way to access your account. You would need to create a new Apple ID, which also means you won’t have access to previous purchases or data stored in iCloud."
