Federal refund

I efiled both Fed & State thru Turbo Tax. I have confirmed emails stating hey had both been accepted. Received the the state refund. Have not received Federal refund. Website says they are still processing on the "Where's my Refund" page. I set up an online account to research further. According to that part of the website, I have not filed at all. I cannot get thru via telephone. I've seen this same question and problem in other posts here. What is going on Turbo Tax and how are you going to help?
