I filed a simple return the end of Jan. I am still waiting on a return and no body can give me answers. I also received a bill from turbo tax for $90, but now they are offering state filing for free?

Regarding your refund, the IRS may have selected your return for additional review. You can check the status of your refund here. You can also contact the IRS directly at 800 829 1040. 

Regarding your bill, it sounds like your return required forms and schedules not supported by the free version of TurboTax.
