balexh, this thread discusses a code 8 Form 1099-R for a return of contribution. Is that what you have? If not, you do not have the same issue and nothing said previously in this thread applies.
It sounds a more like you have a code 1 or code 7 Form 1099-R reporting a regular distribution from a traditional IRA.

TurboTax prepares Form 8606 automatically; be sure to click the Continue button on the Your 1099-R Entries page and answer all of the questions that follow.
