Having your refund sent to someone else's account is a bad idea. Have the IRS mail you a check if you cannot use an account that is in your own name.
If your refund is sent to someone else's account, the bank is highly likely to refuse the deposit and send it back to the IRS. Then the IRS has to issue a paper check to you and mail it to the address on your tax return. That will delay your refund for weeks.
