Hi bookkeeper97,
Thanks for reaching out to us here. QuickBooks Online provides an option to prefill forms with previous data when recording transactions. This feature can be turned off at any time. I would be happy to show you how!
Follow these steps to turn off automation;
1. Open your Settings ⚙ and select Account and settings
2. From the Advanced tab, select the Edit for the Automation section
3. Turn off Pre-fill forms with previously entered content
4. Hit Save, then Done.
Feel free to reach out again, if you have any other questions. We would be glad to assist!
