Since you closed
your business but had assets, the IRS requires that you separately determine
value of each asset (even if just given away) upon disposition so that each is
treated correctly for tax purposes.
In TurboTax, when
going through your self-employed business, be sure to indicate that you
disposed it (the question is located in the Business Profile section ). Then, go the Business Assets section and enter each asset; the program will ask some
general questions, such asset's cost, date of acquisition as well as the
asset's disposition and prior depreciation
questions. (if you wrote off the
full amount in the year you required the asset, the amount is entered in the
179 deduction section (see attached pictures).
