Question about Fees/Products

I was doing the "Free" version like I did last year, but I want to claim the American Opportunity Credit this year -- TT is saying that I need to upgrade to the Deluxe edition for $40.. do I actually have to if I'm just doing that one education credit? Also, why is charging $40 to file state...? I thought I read somewhere that the fee to e-file state (in my case, California) is only 19.99? I know I can delete the state and do it later but it says I have to wait for the IRS to accept Federal.. if I do so, will the CA state fee still be $40 or $19.99? If so, can I file my state elsewhere? I'm thinking of switching to credit karma which I read is actually free...
