Fall term fee paid but did not receive the grants

Basically, the title. However, I had some outstanding balance from the previous session but I was able to request to be on payment plan by the financial aid advisor. It did get approved and they were able to confirm my enrolment. I am quite confused about whether they paid off the outstanding balance or not because I was looking at the invoice for my tuition fee and it doesn't include the outstanding balance from the previous session. I had around $1494.18 as my outstanding balance. I was planning to pay them off through a payment plan where I'd use OSAP and applying to other financial aids to pay it off. So, did they just took my grants and paid it off?
