Get your taxes done using TurboTax

I'm stuck on "Enter Prior Year Roth IRA Contributions"... I already did this in past filings with TurboTax, I don't know why it's asking for them again, nor how long it'll take me to dig this all up again, nor do I want to be double-taxed for them. Why isn't TurboTax seeing my withdrawals and contributions in past years?! I'm under 50. Always some snag with TurboTax.
