It is showing you are using the Online version, with the Online version, you pay for the Federal return & State return, there is no charge to e-file.  The charge is the same whether you e-file or mail in your return. You cannot do 2 separate returns with the Online version under one account.  In order to prepare another return, you would need to create a new account (UserID & Password).  If you use the same account for the second return, then the second return will overwrite the first return.
