Agree with George. As to direct deposit, the only word of caution is that the economic impacts payment will be made in the same manner as social security benefits.
In the event your client is not enrolled in Social Security Direct Deposit and receives the benefits by check, the economic impacts payment, likewise, will be sent by check. If your client then want to receive the advance refund by direct deposit, he/she should use the website George mentioned to enter the bank account details.
