" Did this exemption get wiped out, but irs pubs haven't been updated?"
The exemption did not get wiped out; it is still $600.

With respect to the exemption in TurboTax, that appears to be the result of having checked the "Final return" box. I can reproduce that result (you probably will be able to do so if you uncheck that box).
Obviously, that is not the correct behavior; it is most likely some sort of bug in the program. You can, however, as you have discovered, simply enter the exemption directly on the 1041 in Forms Mode for the time being.
