Hello jsupple,

Thanks for getting back to us. 

When you import sales transactions from Square to QuickBooks, they are added as "Square Item" by default. This item is mapped to a specific income account in your chart of accounts, which helps you track your sales revenue more efficiently. To change the account the Square Item maps to:

1. Click on the Sales and select Products & services.
2. In the Find products and services field, search for Square Item.
3. Under the Action column, select Edit.
4. In the Income account dropdown menu, select the income account you want Square sales to record to.
5. Tick box to update historical transactions.
6. Select Save and close.

These steps should help you edit the income account for Square transactions in QuickBooks Online. Let me know if you need further assistance.
