Get your taxes done using TurboTax

If you are preparing a return and have not yet filed, look for a question toward the end of the federal or state module "are you filing from a recognized disaster area?"

If you can't find it, don't worry.  Turbotax thinks you are late and will offer to calculate a penalty.  Decline the offer, don't take the penalty calculation.  The IRS will bill you later if you owe a penalty, and if you are in  recognized flood area, they won't.
