did you try calling them? what state are you in?

your first issue is to untangle your insurance issue and then and only then resolve any tax issue. You do not need a tax pro currently.
Also, when you go to the doctor, etc, are you verifying your insurance carrier? From what you state, these providers are sending their bills to Caresource for settlement and Caresource is paying them, leaving you with deductibles and co-pays.
If you have insurnace through your employer that is not Caresource, are you paying premiums to Caresource and if so, why? if you were not paying the premiums, they would have notified you and cancelled your coverage, so there is still something missing explanations from your story.
