what the tax experts point out only applies to the years 2018-2025 not to 2017. in 2017 did you file a police report? that's important because if you amend 2017 the IRS may require proof including asking if you filed a police report. it is also possible that the IRS will challenge the deduction claiming you made gifts and therefore do not have a theft loss. I would strongly advise you to consult a tax pro on how to proceed.
