You cannot combine 2015 income information on your 2016 tax return.  Each tax year needs to be prepared separately, using the software for that year.  If you happen to owe anything for 2015, be aware that late fees are adding up.

To file a return for a prior tax year

Only a 2016 return can be prepared online and e-filed. 

 If you need to prepare a return for 2013, 2014 or 2015 you can purchase and download desktop software to do it, then print, sign,  and mail the return(s)

  (if you want to prepare on paper for free:  )

You can download the Forms and Instructions from the IRS web site:

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