Hi, kg2020.

To change the posting account of the retainage, you can create a Sales Receipt or apply it to an open invoice.

Below are the steps to complete the process:

1. Click the +New in the left panel and select the Sales receipt.
2. Select the Customer name from the drop-down.
3. From the Deposit to ▼ drop-down menu, select the separate account you created for retainage, your main operating account, or the account this money will be kept in.
4. In the Product/Service column, select the Retainer or Deposit item you set up.
5. Enter the amount received for the retainer or deposit in the Rate or Amount column.
6. Select Save and close.

For detailed information and additional recommended steps (proceed to Step 4), check out this article: Record a retainer or deposit.

Also, I'm including this article for your other reference: How to view Retained Earnings account details.

I appreciate your time today. Please know that I've got your back if you need help with QuickBooks.
