Please clarify some things. Underneath your question it says "Online Premier", yet you mention a license key.
Did you purchase desktop software, and if so, as a CD or download? Did you purchase directly from TurboTax or another retailer?
Are you installing the desktop software and asking for the license key to activate the software so you can start using the TurboTax desktop program? Or did you use the Online TurboTax website by mistake?

any chance that order number is the license key - the license key is a 16 digit field and the order number you post is that (if that is the case, suggest editing your post and deleting it!)
This WAS VERY Annoying. Your product DOES NOT WORK with OSX!! How can the leading tax software provider not work with MAC? Furthermore, you do not make it easy to transfer the license to the online version. I purchased through Costco with email delivery for a Windows download. There were no options or indications at purchase. Even if there were, Intuit should make it easy to apply the license key to the online version. All I (and millions of others) want to do is license your product. How, after all these years, have you not solved this issue? I am going to post this complaint all over the internet if I don’t get quick remediation or a refund!
