I think there is a rule of limiting loss = 0 when you have a partial year rental property used for pesonal use. So I am guessing (not sure if correct) that even if you added the depreciation your income/loss is still 0. Essentially taking 0 depreciation.
And I think that year's depreciation is 0, so even if you amend, the number wouldn't be changed.
It might be compelete if you file 4562 to document how much the house would be depreciated, and how that depreciation is limited to 0 in schedule E. That way when you sell the house, you show the recaptured depreciation for 2016 is zero, instead of the 9 months you put it in service.
