These are all well and good . . . following the recommendations exactly. My suggestion is to Section 179 as much of it as you can/want when you buy it. When I bought computer equipment, I had the same types of problem -- a 5 year depreciation schedule. Anyone knows that a computer is not useful for 5 years, so I started with Section 179 fo all of it.
As far as the 'office' goes, my guess is that they treated it as part of the house (house is 27.5 year depr, sched.) I have also found that 'Office in Home' almost never a benefit, since you need to take out all of the deductible parts of your house (taxes, insurance, etc. based on the sq. footage of the office (and lose them from your personal), especially if you might ever want a mortgage, since you need to have income amounts for a mortgage, yet prefer not to pay taxes along the way -- a real conundrum. I can't suggest how to fix it except to not use the standard depr and don't bring it forward from previous TT returns, then try manual. Good Luck!
