The TurboTax tax data file from 2016 can be transferred to a 2017 TurboTax New Tax Return regardless of which Operating System program was used in 2016.
The tax data file can be opened by any TurboTax desktop CD/Download edition for the same tax year as the tax data file. So a tax data file from 2016 which has a file extension of .tax2016 can be opened by a 2016 TurboTax desktop edition (Windows or Mac).
