Did you add a state return after making the first payment of $40?   In the Online Deluxe Edition a state return is an additional $40.

Maybe you added a state return or another service?  State is another separate $40 in Deluxe and above.  Or did you buy the Desktop CD/Download program but ended up using the Online version?

Or did you purchase desktop software (CD/download) and are now efiling both Federal and State returns?   If so, in the desktop product there is a $20 state efile fee (except no fee for New York state).    There is no fee to print and mail the state return.
