Severance pay question

I was discharged officially on September 20th, and the civilian told me I should be receiving my severance pay on the 15th or 20th of this month. If it’s the 15th that would mean I would be getting paid tonight. Would I be able to see the severance pay on my pay? Or no due to that being used for active duty pay checks. Thanks in advance. I apologize if this seems like a stupid question.
