Log in to your QBO account. At the top left, it says Help, next to a ? with a circle around it. Click that. At the bottom, click "Contact Us". Type in a brief description and click "Lets talk". It will pull up "quick answers" Scroll past all that and click Which way you'd like contact.
I wouldn't recommend trying the chat. No one ever responds. The best option is "Get a call back". They will call you back, usually pretty quick.
