You're not doing anything wrong, @McCullough.

The % of income button is found in the Rows/Column section when customizing a report. I can guide you through the steps.

The Add Sub-columns for Comparison section mentioned above is changed to Rows/Columns. You'll be able to see the % of income checkbox in this section when customizing your Profit and Loss report.

You may follow these steps:

1. Click on Reports from the left panel.
2. Look for Profit and Loss on the search bar.
3. Click on Customize.
4. Click on Rows/Columns.
5. Tick on the % of income checkbox.
6. Click on Run Report.

That's it! You'll now see the % of income column on your report.

Also, you can save your customized report in your Custom Reports tab by clicking on Save Customization.
