Delete the state and re-add it:
Go to "State" on the left hand menu, look for the option to delete after you click continue.
You will now be able to file.
Sometimes this will reveal errors in the Federal section that were not showing due to the "Form Set" error blocking them from popping up during the review - this may happen after you delete the state.
If you see those errors (usually duplicate W-2s) fix these and finish filing.
You may be prompted to pay for state, this is because state could not be filed before you deleted it and re-added. (This applies to Deluxe, Premier, and Home & Business.)
You would have been able to e-file federal and would have had to paper file state in most cases.
One caveat - this will not work if you have already registered or paid for your state product, but most of the time it will not allow you to pay for state with this issue.
