For a refund you can only to back to 2012. If you owe there are no limitations.
TurboTax Online only
supports the upcoming tax year 2015 and the prior 3 years (2014, 2013, and
2012). The latter 3 have to be prepared in desktop software
(CD/download). Each tax year requires a different year software; i.e.,
2014 can only prepare 2014 return; 2013 software can only prepare 2013 return,
etc. Prior-year returns cannot be efiled; they must be printed and
mailed.
NOTE:
If you prepare returns for multiple years, do NOT mail them in the same
envelope. Mail them separately.
You can see prices for
those 3 prior years at the link below if ordered directly from TurboTax, but
you may also be able to find them at a discount at reputable retailers like
Amazon:

If you locate a company to file the older
returns, be sure it is a reputable company.
You can download the older-years forms and
instructions for free at the IRS website:

If you find 2011 and earlier TurboTax
software, be aware that you won't be able to update it to the final version and
final forms, and you won't be able to download the state program into it.
Also note that if you are due a Federal
refund, it is generally too late to get a refund for 2011 and earlier
years. There is no penalty for filing a late return that was due a
refund.
