Not to worry. If you've already filed and your return has been
accepted, it's too late to change your bank account information for
direct deposit but since the info you provided is for a closed or
invalid account and your name was also not on the account provided, your bank
will return the refund to the IRS and the IRS will mail a refund check
to the address provided in the return. Paper checks generally take anywhere from 4 to 6 weeks to arrive once sent out by the IRS.
