How do I enter the non-taxable portion of a non-deductible Traditional IRA rollover to a Roth IRA in Turbo Tax. My financial institution doesn't calculate this, so I filled out a form F8606, but I can't find a way to enter this information.

You've got something here that is sometimes called a "Backdoor Roth"

A Backdoor ROTH conversion consists of two parts. 

1. The nondeductible contribution
2. The non-taxable distribution

To record the nondeductible contribution in TurboTax Deluxe do the following:

• Federal Taxes >> Deductions & Credits >>Scroll Down to >> Traditional and Roth IRA Contributions
• Select >> Start/Update
• Traditional IRA and Roth IRA >> Select >> Traditional
