Support should be able to get you a license code for the CD's which are causing you a problem with being associated with another account. This is not something new for support. Whomever you spoke with may just be ill-informed.
Try contact support again on Monday and if you get the same answer as before escalate and speak with a manager.
I will also flag this post for review for one of the TurboTax Moderators of this forum who may want to get involved. However, they will not see this post until Monday.
Support is open form 5am to 5pm Pacific time, Monday thru Friday.
