I have to amend a non-resident return to get a refund of the $616 in tax they paid in error.

What does that really mean?  If the 1040NR was prepared correctly and they only paid more tax than otherwise required, the overpayment will be refunded automatically provided they had no outstanding balances with the IRS.

If the 1040NR was incorrectly prepared, prepare the 1040X to show and explain the changes as Bob suggested.  On the "amended" (i.e. corrected) 1040NR, print/write "As Amended" on the top.
