BFS will automatically convert your refund to a check payment and mail it to the address on your tax return. Allow about 4 weeks for total processing.Don't bother calling the IRS about your refund. Once your refund is approved it is released to the Bureau of the Fiscal Service for payment. Communication between the IRS and BFS is minimal and the IRS won't have any information about your refund until about the time that the check hits your mailbox.
