After you file

Wrong. It's not specifically for people to update their DD info. It's to add DD info of you never had any on file. If you had a TurboTax card and got your refund on it you cannot change it you will get a paper check if you had your fees taken out of your federal refund and will have no option to change that. the US department of Treasury put out a statement saying no one can change their direct deposit info that's on the second page of their tax returns because of fraud that could occur.  I posted their statement by a screenshot on the other posts I've made but I can't do it anymore because they're saying I'm spamming it even though I only posted it three times for people. So I'm sorry to everyone but if you had your fees taken out or got the refund advance you're getting a paper check and there's no way around it whatsoever.
