This is a message forum, not live chat. You have to post all the details of your question and wait for someone to post a response.
What is your question? What do you need help with? What exactly do you mean by "a mistake in federal filling"? Did you make a mistake in the information that you entered in TurboTax, or do you think there's a mistake in TurboTax? What exactly is the mistake? Did you already file the federal tax return with the mistake?
