I forgot to input my Twitch Streamer Discount Code and I already filed my taxes. Is it too late to have that code applied?

You would have wanted to start your tax return using the affiliate partner's website. Our agents are unable to apply or issue refunds for affiliate discounts if the return was prepared at the regular TurboTax.com site.
