So you did not notice that you did not actually pay your tax due for those years or that you did not receive a tax refund?
Now you will need to print, sign and mail in those tax returns. They cannot be e-filed. If you owed tax due, you are late, so you can expect a bill from the IRS for the penalty/interest, which will be calculated by the IRS based on when they receive your payment and how much you owed. TurboTax will not calculate that. If you are getting a tax refund, there is no penalty for filing late.
Online preparation and e-filing for 2016 and 2017 is permanently closed. You have to download the software to a full PC or Mac (not to a mobile device) and then print, sign and mail your return. If you already paid for your TurboTax software, you can contact customer support to push a download of the software to you.

When you mail a tax return, you need to attach any documents showing tax withheld, such as your W-2’s or any 1099’s. Use a mailing service that will track it, such as UPS or certified mail so you will know the IRS and/or your state received the return.
