Investors & landlords

So this year I started working after graduation and earned $22,000.  I also earned $5,000 with stocks.  This is why I would like to use my capital loss carryover from last year.  But I did not file for 2015 so I was wondering if I have to forfeit the carryover from 2015 from having not filed or if I can still use it because I have the 2015 1099 form still.
