[DoninGA]

Yes you can use TurboTax to complete prior year tax returns, 2014 thru 2016.

Go to this TurboTax website to purchase a download for each tax year you need to complete - https://turbotax.intuit.com/personal-taxes/past-years-products/

Prior year tax returns can only be printed and mailed, they cannot be e-filed.

When mailing multiple tax years use a separate envelope for each year.

To file a return for a prior tax year

Only a 2017 return can be prepared online and e-filed. 

 If you need to prepare a return for 2014, 2015, or 2016 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

Remember to prepare your state return as well—if you live in a state that has a state income tax.

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.
