More information - I am working on two separate returns (one for me and one for my son). The problem started when I downloaded a large amount of stock transactions into my return. The menu is fast as ever when working on my son's return, which is much simpler. I can clear cookies but I'll bet that's not the problem since one return is fine and the other has the problem. I can switch without exiting TurboTax and experience the slow or fast behavior depending on which return I select.
