For the Casualty Loss and Theft Deduction, the IRS tax calculation subtracts $100 from each casualty loss of personal property. Also:

• The total of your casualty and theft losses on personal property must be more than 10% of your adjusted gross income (AGI). Otherwise, you can’t claim a deduction for that portion of the loss above the limit. 
• Deductible casualty losses can result from a variety of causes such as car accidents, earthquakes, floods, fire, hurricanes, or vandalism. 

In TurboTax, jump to the entry area for casualty loss:

1. Open your return if it's not already open.
