I got an email saying I can get 20% off TurboTax Deluxe. I'm signed into my account but when I press the link it takes me to the default page. How do I get the discount?

When I clicked "Get Discount" button it takes me to the default 2022 Taxes page. I'm already signed into TurboTax when I clicked the link so where is the 20% discount?  What do I need to do to get the 20% discount? Where does it appear? Do I need to enter my payment method first?
