Will fin aid refund affect fin aid next year?

I got a loan refund, almost $1k. When I fill out the FAFSA, will it affect my fin aid because I have like $1k in the bank?
I have to separate money in that bank and the loan refund on FAFSA right? And I’m assuming that I shouldn’t spend this $1k since it’s basically “loans” I have to pay back anyway??
Is this going to affect how much aid I will receive?
Also, I’m curious how this works for the CSS profile?
