You should include Form 1310, which must be signed separately from Form 1040, but there is a chance that the IRS will ignore this Form 1310 and send you a request to provide Form 1310 as if you never sent one. (I suspect that they make this request to restart the clock on needing to pay any interest on a return that waits in the queue a long time before being processed.)
My experience is that the refund check will be mailed to the address on the Form 1040, not the address on the Form 1310.
