Deductions & credits

You would make entries in the Deductions and Credits section of the program.

The question will ask if you were affected by a natual disaster in 2019. However, the text advises you to enter "Yes" if it was declared between January 1, 2018 and February 18, 2020. See the screenshot below.  

You will only be able to take advantage of the deduction if you itemize.  

Casualty Losses   Affected taxpayers in a federally declared disaster area have the option of claiming disaster-related casualty losses on their federal income tax return for either the year in which the event occurred, or the prior year. See Publication 547 for details. Individuals may deduct personal property losses that are not covered by insurance or other reimbursements. For details, see Form 4684, Casualties and Thefts and its Instructions.
