Why do you need to amend 2016 (besides taking off the 2015 W2)?

You still might need to file a 2015 return.  Your age doesn’t matter.  You can do 2015 for freeon the blank forms.  Here are some blank forms & instructions for 2015

Remember state taxes as well.

In reply to VolvoGirl, my exemptions changed because someone else could claim me as a dependent. The person who could claim me did a 1040x and on my 2016 I put I was not a dependent

Ok then take the 2015 income off too.

No.You must file it on a 2015 tax return.

You need to amend 2016 and delete the 2015 W2 and anything else you need to change on it.
