You can call customer support with questions, but if you mean you expect or require one on one help from a tax expert while you prepare your tax return ("walk through the process") , you are asking for the kind of help only available to users of the online "Live" software.
If you need a LOT of help, you might want to request a refund for the CD/download and wait for the online "Live" software to become available in December and then use "Live" online.
