When you purchase TurboTax Home & Business, the first state is free. Extra states require additional payments.
State e-filing is $19.99 per return. Printing and mailing state returns is free.
I only have one state return and the software is trying to charge me the state filing fee.
Are you utilizing Turbo Tax Home & Business?

There is a lot of confusion about this. For the Desktop versions Deluxe and above, it's a free download of one state preparation PROGRAM, not returns filed. You can prepare unlimited federal and unlimited state returns. Some people need to file in more than one state so they have to buy another state program at 39.99. You can print and mail the state for free or each state return (including the first one) is 19.99 until March, then goes to 24.99.
Box says Federal Returns & Federal E-File plus State returns. It does not say state efiling is included. It also says on the back on my CD case in the chart comparing the versions - 1 state product via download (print free or efile for $19.99 each) prices subject to change without notice.
