Turbo Tax charges

This is my first year doing electronic filing and I just want to be sure I understand how the billing works.  I downloaded the desktop Deluxe edition which included the state return in early February.   A charge appeared on my credit card corresponding to the day of that download.  I submitted my Federal tax return last week but (and got a message that it was accepted) but I haven't yet submitted the state return.   All I'm trying to figure out is if amount I've been billed to date is all I'm going to be charged.  Thank you.
