Receiving Student Finance after Overpayment

Hi,
I’ve recently left university after only two months into first year and received a letter saying I’ve been overpaid by £2056, I have set up a payment plan for this for £50 a month.
I’m hoping to rejoin university next year and I’m wondering how this would work in regards to my entitlement and maintenance? I would receive the maximum amount due to my family’s financial background but I’m worried that I’d receive a lot less maintenance causing issues with paying rent next year.
Thank you.
