Thanks Joseph,
That's exactly the workaround I was planning to use if this turned out to be a TurboTax bug, which based on your input seems increasingly likely. I'm of course dismayed that I have 10-15 years worth of such errors adding up to a pretty decent sum. Multiply this by hundreds, if not thousands of other affected TurboTax users and it's not a pretty sight. The problem is that with the automatic transfer of data from the Federal form there's reduced incentive to carefully inspect the state form. With a superficial review you might just assume it's some other state/federal difference. Such a blatant error is not expected. It was just by accident this time that I started wondering why the offset wasn't allowed and started digging into it.
