Unfortunately, if
your return has been filed and accepted, you won't be able to stop the direct
deposit.
However, if it's the case that your direct deposit account information was entered incorrectly, the direct deposit won't be processed, and you'll receive any refund in the mail. Please see the TurboTax FAQ "What if I entered the wrong bank account for
direct deposit?" below, if this is your situation.
