Does every 1099-G have to be reported as income?

I have a 1099-G from my state for $500.  This amount was refunded to me because of an error in my 2014 taxes which was corrected in 2016 using a 540-X.  I still payed way more than $500 in state taxes for 2014.  Is this still income that needs to be reported?  I did have a Schedule A for that year.
