Then I rented it to another, and I still live there.
To clarify, it is being assume that you rented "a part of" your residence to a 3rd party. Even so, the number of personal use days will be "ZERO" unless you used the rented portion of the property for your personal use *AFTER* you converted it to a rental. If you did not, then that portion of the property is ONE HUNDRED PERCENT business use.
Also, note there is a screen where you are asked for a 2nd time, what "percentage of time" the property was rented for the year. In your specific case becuase you are renting "a part of" your residence, that question should be asking percentage of floorspace - not percentage of time. So enter percentage of floor space. Otherwise, your first year depreciation will be wrong and the program will *not* flag it. (But the IRS will if for some reason your return gets flagged for something such as a random audit)
