Where to deduct unused leasehold Improvements

[cfsadvsr]

I know it is a deductiion when the business owner relocates after 5 years in a leasehold improvement slated for 39 years. The question is how. Is it merely a deduction on Schedule C? and if so, how would it be designated? Or, can it be done from the depreciation schedule. If so, how do you account for the relocation date on the 4562?

Take the remaining basis

as a loss on form 4797. Your software should handle this.
