@toney35, no, I didn't end up amending. I looked around a little more and all the information I could find seemed to match well with what @macuser_22 said above. Essentially, as long as one documents the recharacterized contributions as non-deductible in form 8606 and includes a note explaining the recharacterization (Line 4a Explanation Statement), then there's no need to amend. However, if you hadn't done those things, you should probably amend your return and do so - at least that's my takeaway.
If anybody from TurboTax is listening, it would be nice if some of these messages are better explained. "You may need to amend your old return" isn't very helpful. Plus, you'd think TurboTax could just look at my previous return and determine what I did or didn't do.
