How can I key in a deposit with applying it to a payment

Hi there, colleen-smith44.

Thank you for stopping by the Community this afternoon, I'm happy to help you out this afternoon, follow along below to record a deposit. 

Step 1: Put transactions into the Undeposited Funds account:

If you haven’t already, put the invoice payments and sales receipts you want to combine into the Undeposited Funds account. This account holds transactions before you record a deposit.

Step 2: Record a bank deposit in QuickBooks to combine payments:

Each bank deposit creates a separate record. Make deposits one at a time for each of your deposit slips.

1. Select + New.
2. Select Bank Deposit.
3. From the Account drop-down▼menu, choose the account you want to deposit the money into.
   
   
    
4. Select the box for each payment you want to combine. Make sure the deposit total and selected payments match your deposit slip. Use your deposit slip as a reference. Remember, only select payments you need for each deposit.
5. Select Save and close or Save and new.

Important: All transactions currently in your Undeposited Funds account appear in the Bank Deposit window. If you don’t see one you need to add, put it in the Undeposited Funds account.

You can find these steps, as well as additional ones on this process and how to proceed further at the following link: Record and make Bank Deposits in QBO.
