Alternatively, could I create a new 2016 taxpayer and auto populate it using my 2016 data? I know I could just create a new taxpayer and key everything in all over again but I'm looking for a less labor intensive method.
You can do this in the TurboTax CD/Download versions, but be very careful. You should first save your return with another name and make a copy your return by selecting Save As (or Duplicate in Mac) from the File menu.
You can also use the What-If-Worksheet in your 2016 software to try out scenarios without making a copy. You can find that by going to the Forms mode (Upper left corner in a MAC) and searching for it . See the screenshots below.
