Out of State 1099-G

I received at 1099-G from the state of California. We did not live in California during 2016, or 2015. We moved to Texas in 2014. We sold our house in California in 2015, which caused me to file taxes in California for that year. We received a credit on those taxes (filed in 2016) which is why i received the 1099-G. My question is, do I need to claim this somewhere? If so, where and how? I am not planning to file taxes in California because we have not lived there in over two years. Please help!
