starting a seller account for my business

Ive had a personal prime account for years. I registered an llc, got a business license, a business bank account and a mailbox at the ups store for selling online. I heard you should keep your seller account separate from your personal amazon account. If I sign up for a seller account they get my personal info as well. Will amazon flag this for some reason. I called amazon but the robot that answers the phone now told me to use seller central and hung up on me. I would ask them what to do but apparently you can’t until your a seller.
