the correct way to do this is to amend the 2015 return corrceting the mistake and then the federal carry-over worksheet will bring the correct information to 2016 --- this may mean that you have start the 2016 from scratch for the new federal worksheet to take effect --- ( this best done on a desk-top version for both 2015 and 2016 ).;
the second way is to start 2016 with fresh asset worksheet ( with the correct figures) and say that this was put in service in 2015 -- TurboTax will compute the correct depreciation for 2016. You will still have to amend the 2015 to set the record straight on IRS files. Hope this helps
