My deductible home mortgage interest was calculated to be $35215 in the worksheet. However, the TurboTax Deluxe had decided that I should take standard deduction of $24400, despite the total itemized deduction is much higher than this. This will happen when I clicked "continue" after the question "do any of these sutuations apply to you? you may need to limit the deductible mortgage interest...". If I just save at this point without clicking "continue", I will be able to use itemized deduction. This seemed to be a serious bug. Can someone please confirm?
