Hi there, accounts617.

QuickBooks Online offers users the option to import specific types of data, including invoices, sales receipts, and expenses, to manage new transactions. However, uploading Income entries directly to QuickBooks Online via Excel isn't possible.

We can manually edit the existing income transactions, which allows you to quickly find and update your income transactions individually or in bulk.

Aside from that, you can also use a third-party app to bulk edit or update existing transactions in QuickBooks Online.

Let me know if this covers everything or if more adjustments are needed.
