How can I leave notes on a month to show natural disasters perhaps affecting the revenue?

I appreciate you for posting your concerns here, cozybinstore. Allow me to provide a workaround for adding notes to monthly revenues within QuickBooks Self-Employed.

The first thing to do is to categorize all transactions into income or revenue. This will help the QuickBooks Self-Employed identify your income for the month. Second, create a tag to help you track your sales and expenses into deeper insights. 

Here's how:

1. Go to Settings ⚙ and select Manage Tags.

1. Press the Create New Tags.
2. Enter Tag Name. Example: Bad Weather.

1. Choose the Ungroup option then a color.
2. Once done Save.

After that, Run a Profit and Loss report filter for monthly. Once done, Add the newly created tag to the report.

Furthermore, the result will show up like this:
