Can I deduct homeowner losses due to fire, wind, water damage, etc.?
TurboTax will help you determine if you can deduct a casualty loss.
To enter the amount you go to Federal Taxes (Personal if using Home & Business) > Deductions & Credits > Explore on My Own and scroll to the Other Deductions & Credits section. Click on Start next to Casualties and Thefts and answer the questions to calculate your deduction.
