I figured this out - it's form 8606 from previous years where I see my non-deductible amount I contributed to my IRA's that I then use as my basis for the roll over so I am not double taxed.   Also, by going directly to this form in TurboTax, I found where I enter this basis.

If you contribute to a Traditional IRA and convert to a Roth in the same year, you will not be able to deduct your contribution to the Traditional IRA that year.  This is because any amount converted to a Roth is considered taxable in the year of conversion (even though there is no tax penalty for conversion). In certain rare cases you were able to spread the conversion out over 2 years.  So if you contribute and then convert, it's a wash.

Thanks - I figured out my question (it's a bit different than what you answered, but I do appreciate it) - it's form 8606 from previous years where I see my non-deductible amount I contributed to my IRA's that I then use as my basis for the roll over so I am not double taxed.   Also, by going directly to this form in TurboTax, I found where I enter this basis.
