Or are you using the Desktop program? There is a 24.99 fee to efile the state return in the Desktop program. And if you are in California and want the fee deducted from your federal refund you have to add Premium Service. So pay the fee with a credit card or print and mail state for free.
Go back through the File tab again and change to pay with a credit card. Then if Audit Defense is still there you can remove it.
