I'll work with you to find out what's causing the double amounts on your reports.
I take it that you're referring to your Profit and Loss report. In this case, you'll want to drill down the amounts by double-clicking on them. It'll give you a detailed view on the transactions under the certain income account.
If there are transactions that were recorded twice or incorrectly, you'll want to delete them to correct the amounts.
On the drilled-down Profit and Loss report, double-click on the transaction. Then, click the More button and select Delete.
Also, you might want to check those banking transactions that were added instead of being matched to a record in QuickBooks. This can also cause the double amounts in your Profit and Loss reports. Here's how:
Go to the Banking tab.
Click the Categorized tab.
Double-check the added transactions.
If there are transactions that were incorrectly added, check them then click the Undo button.
They will be added back to the For review tab. Simply match them (if they are supposed to be matched with a record) or exclude them (if they aren't supposed to be added to your books).
I'm at the ready if you have more questions about the data on your reports or in QuickBooks Online. Just reply here and I'll ensure you're able to finish your tasks and get back to business.
