CRSC is deposited to the same account where you receive your retired pay or direct deposit. You can change that by logging into your myPay account or I can get you a phone number to call if you'd rather do it verbally or via mail.

If they've got it screwed up somehow, you call 1-800-321-1080 to give them the correct account information.
