Good day,
I am sorry that you have experienced a theft of your crypto holdings.
There was a time when you could deduct a casualty loss for the theft of property. However, the Tax Cuts and Jobs Act of 2017 eliminated casualty losses for most taxpayers (there are exceptions for taxpayers effected by Federally Declared Disasters). As such, you can not deduct the loss resulting from the theft of your crypto.
This is a new Turbo Tax Resource that may answer other crypto questions you have.
