After you file

that's exactly what i did

 

i made the initial purchase of $42.65 (turbotax desktop basic) +  the second payment for $31.99 (deluxe upgrade, inc 1 free state) = $74.64

 

and the third payment was  on that final page for $47.98 (where i opted to pay for it with credit card)

 

and i checked my return maybe like 20 times before submitting it

 

WHERE OH WHERE was the information about charging me those processing fees from tpg. NO WHERE did i see them. and even for my final check through, i did it together with my brother, who also did not notice anything about those processing fees.
