FYI, I asked on AA twitter and got this response:
EDIT: so I cancelled and went to the link they sent, put in my ticket number and last name, it shows the details including the payment information but my only option is to cancel and won't let me move to the next step, with an error telling me to contact AA to reinstate miles (it's a revenue ticket, not a miles ticket)
EDIT2: Contacted the EXP desk and they put in the refund request for the full amount and added the SWUs back in to my account in about 2 minutes.
