I got my Vanguard 1099Rs and called to complain about being coded as "1" (no exception) instead of "2".
They said pretty much what Intercst said -- they were told by IRS not to use "2" anymore - use "1" and let the taxpayer deal with it using form 5329.
Maybe instead of using the poor excuse that they were told by the IRS, Vanguard should do their own tax research like I did. Looks like a typo on the part of some shmuck at the IRS on the original instructions. You'll see the instructions back to normal next year, I'm sure. I posted the answer below, but you can get it at the source almost at the end of the page at
