Yes, some people are getting this error message. This could be due to the state return that you are e-filing along with your Federal return. Your state return may not be ready yet. To fix this, e-file your Federal return and change the filing method for state to file later.
Please see this TurboTax FAQ, for more assistance, Can I file my federal taxes now and skip my state for later?
Also check the State Form Availability Form Table, for when your state forms will be ready.
