Depreciation works on a fixed schedule as provided by the IRS. You go changing things and it's a sure fire guarantee of an audit 24-36 months down the road after filing.
If the shown depreciation is not correct, then it's because you entered incorrect information pertaining to that depreciation. Depreciation is figured based on the data you enter. So either you entered a wrong monetary value for that asset, a wrong in service date, or wrong business use percentage.
If on the primary property, then most likely it's because you incorrectly indicated you had more than zero days of personal use. (this is the most common mistake).
