I filed my own tax return on 2/7 and Form 8606 worked correctly at that time. It correctly calculated the gross and taxable parts of distributions. And I had both basis in IRAs and a partial Roth conversion thrown into the mix.
I just re-opened my return and observed the same problem that you are reporting. Now it is only showing the taxable part of the Roth conversion as income on the front of 1040. The taxable part of other IRA distributions is MIA.
This is a MAJOR problem and is in need of a fix pronto.
And I am so disappointed that I am not getting literally thousands more in the form of a refund...
