Why does the Turbotax service not let me review and complete my return? The page goes blank, and I cannot continue? Should I just go with H

I have double checked all fields and cleared and resubmitted my info, cleared cookies, changed browsers.  This is bad programming, bad user experience, and just not acceptable.  The screen goes blank when we get to the final review before we file, and there is no error, no message at all to tell me what is happening.  It tries to load something for a second and then just goes blank.
