you can't take the HO deduction unless the space is used exclusively for her office for the entire year. the first step is to make note of the depreciation taken in prior years. if you sell at a gain the depreciation must be recaptured even if it's 20 years down the road. but TT won't know about it. then if the was no s-e activity for the whole year just delete the schedule C.
Open or continue your return in TurboTax.
In the left menu, select Tax Tools and then Tools.
In the pop-up window Tool Center, choose Delete a form.
Select Delete next to the form/schedule/worksheet in the list and follow the instructions.
