TurboTax does not support tax year 2016. It only supports tax years 2022 thru 2019.
You could possibly get a 2016 TurboTax software from an online retailer. However, there will not be any 2016 updates available nor 2016 state programs available.
If you need to file a 2016 tax return then you should seek out a local tax professional in your area to assist in completing the 2016 tax return. Also, the 2016 tax return can only be printed and mailed, it cannot be e-filed.
