Itemized deductions for Hurricane Harvey are being included under a Standard Deduction of over $66,000. Is this normal?

I have input damages from Hurricane Harvey and Turbotax is showing a "Standard Deduction" of over $66,000.  I assumed that the Standard Deduction would not change and the damages would be itemized as a casualty loss.  Why is Turbotax listing the Standard Deduction so high and not listing as itemized deductions?
