Hey guys,
I finally found out what's going on. I downloaded 1099B form from chase account and saw that it's actually from "JP Morgan Securities"! I thought mine belongs to Chase because this brokerage account is on the same page with my Chase bank accounts but it turns out not. So please check the top page of your 1099B form to see where your brokerage account is located at. I was able to connect TurboTax with JP Morgan Securities with my chase.com login ID.
Good luck!
