I was scammed out of 3800 due to a crypto scam. Some of the money was directly mine and some had been given to my dependent to invest for us. Why is it not showing up ?

When the tax laws changed for 2018 and beyond, theft losses were eliminated as a deduction on federal tax returns.

You're not seeing a deduction for your theft loss because the deduction for personal casualty or theft losses has been repealed in tax years 2018–2025, unless the loss occurred in a federally-declared disaster area.

 

Previously, uninsured losses exceeding $100 due to fire, theft, or natural disaster could be deducted if the total loss amount exceeded 10% of the AGI, regardless of location.
