After you file

There's a statute of limitations on getting refunds on tax returns.  You may want to check with your particular state as to how many years back you can still get any refunds due to you.  

Federal returns its 3 years, some states are different.  CA gives you 4 years, but I think each state is different.

I would absolutely get them filed correctly as soon as possible and see what happens.  Its never too late to file a return that hasn't actually been filed yet.  Worst case is you don't get anything back, but chances are, with only 3 years back, you should still be in the statute of limitations.
