Right, that all makes sense. I've been using TurboTax since the 1990s so I would have been pretty familiar with it by 2010. I think it would have to have been something really easy to miss, although clearly I didn't enter anything. I do remember doing this conversion and specifically choosing to split the tax liability over the next two years, so I'm sure I would have remembered doing anything consciously as far as entering the balance or not.
