Automatic Renewal

Question: I currently have the Internet Security installed on my computer for 2011. I'm getting repeated notices about renewing. However, when I purchased the original package, I thought I had selected the automatic renewal feature. Now I'm not sure? How can I check to see if this is activated on my account?  I don't want to renew ahead of time, if it's already going to be deducted from my credit card. Thanks!
