overcharged for filing

I paid $70 which I thought included 5 federal returns and 1 state return.  However, I was charged an additional $39.98 (19.99 each) for filing 2 state returns.  I understand the $19.99 for the second state return but should not have been charged for the first state return (19.99).  But, I suppose you live and learn..... But easy to complete tax forms and e-file.
