Hi, Trish. Welcome to the Community! I'm here to ensure that everything aligns perfectly with your needs. To get started, I have a few questions to accurately address your concerns regarding the deletion of a data file.
When you mentioned you started a new data file, were you referring to creating a new company file? If so, is it within QuickBooks Online or QuickBooks Desktop? Additionally, have you come across any duplicates or inconsistencies in areas of QuickBooks other than the bank account?
The more detail you can provide, the better I will understand your situation and offer the most effective solution. Feel free to include a screenshot for clarity.
In addition to this, if you need to manage multiple transactions efficiently, you can utilize the batch processing feature which allows you to quickly delete or void multiple transactions simultaneously. For more detailed guidance, please refer to the following resources:
I’m eager to hear back from you so we can proceed and ensure everything is set up just right. Wishing you a great day ahead!
