How to split deposit when matching

Hi all, I just switched to QuickBooks this year, so I'm still learning the ropes. I run a service business, where I often collect payment day of in form of cash or check.

I recently made a deposit with several different payments of cash and check. Normally this isn't an issue to split. However this time, most of the payments I placed in "payments to deposit" at the time of receipt. One of the checks that I deposited with them I had not placed in payments to deposit, because it doesn't belong to an actual invoice in the quick books system. It was a roll over payment from 2024, and my accountant just created a "transition" customer with an outstanding balance equal to my old uncollected payments. So I somehow need to match the deposit as both a transfer from payments to deposit, as well as a received payment to the "transition" balance. I can't quite figure out how to do that.
