TurboTax does carry this information forward on the IRA Information Worksheet, but it's all to easy to cause TurboTax to silently delete this information after transferring in from the previous year's tax file. All it takes is mistakenly answering No when TurboTax asks if you made nondeductible contributions for a prior year and TurboTax will remove the information without any indication to the user that it has done so. If that happens, you must add it back manually or start your tax return over completely and transfer in again.
