Took advantage of the option to move the pre-tax portion of my traditional IRA into my employers 401k (they allow it). I did this so I could separate it from the after-tax contributions I had made over many years (yes, I had co-mingled pre and after tax contributions in my TIRA). The remaining after-tax portion was then rolled into my Roth IRA. Recap: pretax $ went to my 401k, and after-tax $ went to the Roth. I received two 1099-R's from Vanguard: the one for the pretax rollout to the 401K (Line 2a - shows not taxable (seems correct); but the second 1099-R for the portion that went into the Roth (line 2a - shows the entire amount as taxable, Line 2b box "Taxable amount not determined" is checked). Vanguard says they consider any rollouts from an IRA as taxable and have no way of knowing or differentiating pre from post tax contributions, and the transaction confirmation document" refers to it as a "rollover conversion" if that matters. The money did all end up in the right accounts so no errors in that regard.
Aside from the above, how do I enter these two transactions in TT to make sure I'm not taxed a second time on the portion that went to the Roth, and how I can check it for correctness?
