TurboTax no longer supports tax year 2012. You may be able to purchase the software from an online retailer such as Amazon. However there is no guarantee that you will be able to get any updates or download the state program.
Note - If you are only filing the 2012 return for a tax refund, the time to file for the refund has expired. A 2012 tax return with a tax refund had to be filed on or before April 15, 2016.
For tax years 2014 and 2015 you can purchase a software download of each tax year from this TurboTax website - https://turbotax.intuit.com/personal-taxes/past-years-products/
Prior tax years can only be printed and mailed, they cannot be e-filed. Use separate envelopes for each tax year when mailing the tax returns.
