2022 small business my storage unit that housed my equipment was stolen. I got a settlement from public storage but did not cover all my losses. Can I deduct my loses

Yes.  You report your unreimbursed business theft loss in TurboTax as follows:

In TurboTax CD/download, select Personal, then Deductions & Credits, then,

1. Scroll down the screen to Other Deductions and Credits.
2. Select Casualties and Thefts.
3. At the screen, Casualty or Theft Event, select the option for Income-Producing Property and continue to enter your information. 

If you are using TurboTax online, the process is similar.   After signing in, select Federal (left margin), then select Deductions & Credits.

1. Scroll down the screen to Other Deductions and Credits.
2. Select Disasters, theft, and other property loss or damage.
3. At the screen, Did you have anything damaged or stolen during a recent federal disaster?, select Yes.
4. Then continue to enter your information.

In order to claim a theft loss deduction, the taxpayer must prove:

1. that a theft occurred under the law of the jurisdiction wherein the alleged loss occurred, 
2. the amount of the loss; and 
3. the date the taxpayer discovered the loss.

The taxpayer bears the burden of proving by a preponderance of evidence that a theft actually occurred.
