Retirement tax questions

Three weeks since the last post on this issue, and I still cannot file my taxes because of this bug.  TurboTax mistakenly calculates a $6000+ penalty.  It's inconvenient that TurboTax hasn't fixed this even though it's been known for a month or two now.  But what's really inconvenient is that TurboTax has not made the information easily accessible to its front-line techs.  I wasted about three hours dealing with techs who were using my tax return to 'discover' and document the bug as if I were the first person to encounter it.  I don't know why it's so hard to fix this, but it seems like it would be fairly easy to trigger a warning that this is a known bug.
