Hi there, Hannah.

The option to split the Memo and the Description column is unavailable in QuickBooks Online. As a workaround, you can export the Transaction List with Splits report to Excel so you can separate it from there. You can follow the steps provided by my colleague above.

For additional resources, here's an article about customizing your reports in QuickBooks Online.

You can also memorize your report to save its current customization settings.

I'm just a few clicks away if you need further help with managing your reports.
