To use TurboTax for completing a 2016 tax return you will need to purchase and download one of the 2016 desktop editions from this website - https://turbotax.intuit.com/personal-taxes/past-years-products/
A 2016 tax return can only be printed and mailed, it cannot be e-filed.
If you are filing the 2016 return with no taxes owed or for a tax refund there is no penalty for filing after the due date.
