Was it an improvement or a repair? A repair maintains the property in as-is condition. An improvement, also called a "betterment", increases the value of the property, or extends the useful life of the property. For a home office, an improvement might apply to the entire home (a new furnace) or it might apply only to the space used for the home office (new energy efficient windows, for example). Improvements are added to the cost basis of your property and then depreciated over time, the amount of depreciation depends on whether the improvement is allocated 100% to the home office or on a percentage basis.
Did you have an improvement or a repair, and did it cover the entire property or just the office? There should be a place to enter improvements separate from repairs, but I haven't used that section of the program, someone else can tell you where it is.
