You should not file your state tax return if your federal tax return is not complete and final. The state tax return takes information from the federal tax return. If you file your state tax return before your federal tax return is complete, some of the information in the state tax return might turn out to be wrong. In addition, if you make changes to your federal tax return it might automatically change the state tax return in TurboTax, so it will no longer match the state tax return that you filed. You would then have a very messy situation where you have to amend your state tax return, but you no longer have the original state tax return in TurboTax.
I strongly recommend that you wait to file your state tax return until you have finished your federal tax return. If you have not already missed the state filing deadline, file an extension for the state tax return.
