When yhou inherited it, it most likely became your personal property. For example, if what you inherited was the house of the deceased, then it became your personal property. Losses on the sale of personal property are never deductible and don't even have to be reported on your tax return.
However, the transfer of more than $10K from a foreign bank does have to be reported to the treasury department, and that has absolutely nothing what-so-ever to do with taxes. If you did a wire transfer then you can rest assured the U.S. bank receiving the funds has reported it to the treasury department already.
