I have a habit of not clicking on links in a user forum so I didn't review the site you posted.
First of all, there are a lot of scam sites, so you have to be careful to do the homework first. If Brad's Deals is a legitimate site with a legitimate discount offer, then usually with affiliate partnered discount portals, you have to begin your return at the special discount page at the affiliate's website. That's how it knows to apply the discount.
If you already started at regular TurboTax portal, then you can try the following. This is what I tell folks who have started before they discover that their bank, travel club, brokerage, insurance agency, etc. offered a special discount portal.
Lot out of all Intuit accounts including this forum.
Delete all Intuit cookies and empty the browser Internet cache.
Close the browser and reopen it.
Go the special discount portal page. Do NOT sign into TurboTax account before going there.
Only sign in after you reach the discount page, and it asks you to log in.
And as I mentioned above, be sure it is a reputable legitimate site and offer.
If it's not obvious that you are getting the discount, you can go to the FILE section as though you were going to pay, and look at "Review Your Order."
Also, each time you work on your return, go back to that same special portal website to sign in and eventually pay/file the return.
