Does your question mean that you did not file a 2015 tax return, and that you now want to do so (or need to do so)?
If true, this can easily be done with TurboTax software -- but only by using the 2015 TurboTax desktop product (installed from a CD-ROM disc or a direct software download to your computer). This is so because the 2015 online (web-based) internet version of the product line is no longer available for 2015, having been replaced on the TurboTax website with the current tax year (2016) software.
Also, while the IRS and your state department of revenue (if applicable to you) will still gladly accept 2015 tax returns, until 3-years beyond the original filing deadline in fact -- making that filing date April 18, 2019 -- the e-file window is closed now for the 2015 tax year. So, any 2015 tax returns that taxpayers want to file, must be physically printed and sent by traditional postal mail.

The information above is one valid way to complete and file your 2015 taxes.
Another way is to use a competitor's prior year tax software. An additional option is to seek out a local, professional, income tax preparer or firm. A final choice is to download the necessary blank tax forms and instructions from the IRS.gov website (and your state department of revenue, if applicable) and fill in the tax forms by hand. However, we would recommend that last option only for those who either have very simple tax returns, or who just enjoy the tax preparation process itself (as completing most tax forms by hand is a lot of work!).
Thank you for your inquiry.
