Yikes. You only needed to buy 1 CD. The Desktop program can do unlimited returns. Yes there is a 24.99 state efile fee in the Desktop program or you can print and mail state for free.
Are you both in the same state? What you get is one free state program download to prepare unlimited state returns. Then each state return including the first one is 24.99 to efile. It was 19.99 before March 1.
You should try to get a refund for the second CD. It won't let you install the second CD on the same computer.
