Yes, you recognize the unamortized portion of an intangible as a loss in the year the business closed.
In TurboTax, you indicate that you disposed of the asset on the date the business closed, and the proceeds were "0" and the cost basis is the unamortized balance.
See this section of IRS Publication 535 for more information on the disposition of intangible assets.
