Where do I get that information?
Your GI Bill Statement of Benefits will show you how many of your benefits you have used and how much you have left to use.
ok and are there other GI Bill programs that you may qualify for?
of course, there is the Montgomery GI Bill Active Duty MGIB - AD program. If you have served active duty for at least 2 years, find out if you are eligible for the Montgomery GI Bill Active Duty program.
