Hello, @buckvantrease.
Are you referring to the Adjust Row Amounts feature in QuickBooks Desktop (QBDT)? If so, we don’t have this feature yet in QuickBooks Online (QBO). That’ll be a great addition to the current features that we have in QBO, so I’ll be sure to take note of it and send them to our Product Development team.
For now, you can visit the QuickBooks Blog to check for new updates and features that we have.
Here's more information on how to create budgets in QBO: Create and import budgets into QuickBooks Online (Plus and Advanced).
However, if you mean something else, let us know below. I'm always here to assist.
