Business & farm

I had a NOL in 2012 from my small business. I thought it was carried over and used in 2013. I just checked to see if there was anything left for this year and spent hours going through everything back to 2012 where I saw on the Federal Carryover Worksheet for 2012 where it should be there is nothing. How do I fix the Carryover worksheet for 2012 then apply all the NOL carryover to 2013? 2013 would use it up so nothing would remain for carryover.
