You can get to the correct page by typing in the address directly, even though the gear icon is not working.  /exportdata is what you need I believe.  I found the address by navigating to the page in chrome and then went back, signed in with IE, and added the correct address.

That said, once I got through the process, it still doesn't give you your data.  It says that Intuit has to review the request and make sure the data can be exported, which usually takes 12 hours.  I'm still waiting a week later!
