How do I indicate on my tax return I qualify for IRS declared disaster area, Treas. Reg. §301.7508A-1(d)(2) ?

Do you have a casualty loss due to a federal disaster?  Go to Federal>Deductions and Credits>Other Deductions and Credits>Casualties and Thefts

Click start and then go through the screens to enter the losses you have as a result of being in a federally declared disaster area.
