If it's available for redownloading then it will show in the Purchased section : go to the Purchased link under Quick Links on the right-hand side of the iTunes store homepage, or on the current version of iTunes you can click on your id towards the top right of your iTunes and then click Purchased on the popup :
If it doesn't show there then check to see if you've hidden it : iTunes Store: Hiding and unhiding purchases - Apple Support
If it's not hidden then you won't be able to redownload it
