Sorry Online is only good for 2018 now.

You can only buy the download for prior years.  You need a full Windows or Mac computer to install it on.  Buy the download here     https://turbotax.intuit.com/personal-taxes/past-years-products/  

You have to print and mail prior year returns.  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 received the return.  Don’t forget state.

If you are getting a refund, there is not a penalty for filing past the deadline.  You have 3 years to file for a refund.  If you owe taxes, the interest/penalties will be calculated by the IRS based on how much you owe and when they receive your return and payment. The IRS will bill you for this; it will not be calculated by TurboTax.
