I just got this help from a Quickbooks Help chat. Find the client ID in Chrome by navigating to the client you want to export and using "Ctrl+Alt+?" In internet Explorer, paste:
https://qbo.intuit.com/qbo16/external/qbo4a/openCompany?internal=true&companyId=ENTERCOMPANYIDHERE
Replace "ENTERCOMPANYIDHERE" with the company ID you pulled up in Chrome. No spaces, just the numbers. This will navigate you to the client in Internet Explorer and let you export. Hope this helps someone! The Quickbooks chat was very kind and helpful.
