Why am I being charged two different prices for my fees. I downloaded my forms and it shows me that I will get back $907 now it's showing different.

I was charged $78 total for my fees. $25 for ERPs fee, $30 for EPs fee, and $38 for turbo tax fee. Now it is showing $43.20 for ERPs fee, and $41.04 It is now showing a different price of what I would get which is $888.76. How can you charge me two different prices.
