Can I fix the mess in Quickbooks? I added a lot of payments manually and now there are a lot of "matches" lying there that are making it messy.

Quickbooks and accounting is new to me. I volunteered to manage monthly levies for a housing complex but I've made a mess and want to clean it up. I have a lot of bank transactions that need matching but I'm worried I will create further chaos with the customer balance if I match the payment.
