Thanks for your reply. Couple of points here to note based of what I was told by OR state IRS office person. There is a box on the tax form that asked if you had filed for extension. That box on the form wasn't checked by turbo tax software and that is why OR state is charging me interest starting from July15th on overdue taxes. I was told by them that if I can provide proof of extension filing, they will refund the interest amount I was charged.
Moreover, I actually didn't owe any taxes. It was TurboTax software that miraculously turned my ~$5K refund into ~$500 in taxes due. It was caused by adding my second 1098 form. If at all , my refund should have been increased by adding another mortgage interest to my deductions.
NOTE THAT: I paid for the software and I am not a free customer using free version of your software.
