TT Online Discount from Fidelity does not seem to be applying. I've been using the instructions, but site still wants credit card, does discount appear after that screen?

I have cleared the browser cache/cookies and made sure I have clicked the link on the fidelity page when logging in. I filed an extension for this year, and it gave me the option to skip the payment until I file, but I want to make sure I still get the discount. I'm nervous about inputting my credit card, clicking "continue" and then it charges the card on the next screen automatically.
