Welcome to the Community, @sara526. I've got some insights to share about recording sales from Amazon.
I understand that it's quite challenging because Amazon has lots of different transactions that made up that amount but deposited in one net amount into QuickBooks.
To get more meaningful information from your financials, you'll want to break these to get a true picture of your profitability. You can download the settlement report from the Amazon sales website.
The report will let you see the breakdown of your income that you're receiving into your bank account. Then, enter these transactions by using a sales receipt or create a journal entry to post the details.
I'd recommend reaching out to your accountant for further assistance. They can help you in categorizing the fees and the sales taxes to their correct accounts.
For future reference, you also want to consider using a third-party app that can integrate with Amazon sales. You can visit the Intuit App Center and type a keyword like Amazon in the search bar.
Let me know if you have additional concerns with recording your transactions in QuickBooks Online. I'll be here to helping you more.
