It's not clear what your question is. You didn't actually ask a question. But you can be sure that TurboTax did not file your federal tax return twice. The message that it displayed might not have been clear, or you might have misunderstood it. If they did try to file your federal return again, it would be rejected. In any case, there is no confusion with the IRS, so don't worry about it.
Make sure that your state return has been successfully filed. You should get two emails, one saying that it was transmitted, and the second saying that it was accepted. Or you can check the e-file status. Some states are slow processing e-filed tax returns. It can take a few days for it to be accepted.
