form 8606 bug

Anyone else notice a bug in populating form 8606?  I did a small Roth conversion this year and have a small after tax basis that I had been tracking.  In Turbotax retirement income, the taxable amount was calculated correctly however I just noticed (after filing already) that my form 8606 part 1 is blank and the only thing that is populated is part 2 which indicates the entire amount is taxable.  Do I now have to file an amended return to correct that?
