If you didn't report your rental "at all" on the 2016 return, then you will have to enter everything manually on the 2017 return. If the figures you quoted are off the 2015 form 4562, then when entering the data in the 2017 program the prior year's depreciation already taken will be the sum of $15,008 plus the $1810 in depreciation for the 2015 tax year. The reason that number needs to be right, is because you have to recapture that depreciation and pay taxes on it, in the year you sell the property. If it's wrong, you can bet your sweet bippy the IRS will catch it (usually 2-3 years after you file) and audit you on it.
If you did "NOT" report the rental at all on the 2016 return to show it's conversion to personal use, then at this point I really wouldn't worry about it. Don't recapture depreciation for 2016, since it wasn't rented out in 2016. Then, if you do get audited on that, all you have to do is amend the 2016 return to convert the property to personal use on Jan 1, 2016. That stops the depreciation. Of course, then you'll have to amend the 2017 return just to "show" you converted it back to rental property on the date the CO was issued.
