I appreciate you getting back to us and performing the steps provided by my colleague, @Kirkk. Let me share some clarification about the received payments in QuickBooks Online (QBO).

As my colleague mentioned above, after receiving the payment for the invoice, you'll have to add the category under the Add funds to this deposit section. From there, you can select the expense account you created on the Account dropdown.

I've attached this article to serve as your guide in recording bank deposits in QuickBooks Online: Record and make bank deposits in QuickBooks Online. This will also give you instructions on how you can edit or delete a deposit.

I'll also add this article you can refer to if you want to review your downloaded bank and credit card transactions and put them in the correct accounts: Categorize and match online bank transactions in QuickBooks Online.

Post again here if you have additional concerns about entering deposits. I'd be happy to assist you further. Have a great day ahead.
