I am not sure what she did, but I did not enter half of the cost basis. We did claim half of the income, expenses, taxes, fees, etc. So I guess my mistake was the cost basis, but I would have thought TurboTax would have walked me through that since I indicated I owned half of the property. Yes, both names on the mortgage and the title. So it sounds like I won't be using TurboTax this year if I need to file a 3115 or amend previous year's returns. Thanks for your feedback.
