Hello, Annabelle3030. 

I understand how inconvenient it can be when encountering errors while doing tasks to your account. I'll be sure to help provide additional steps to fix this.

A few reasons why you encountered an error in the 1099 workflow are the following:

• invalid characters or missing fields in your Company's business name
• improper format of the EIN or tax ID

You'll want to review the information to see if there are any missing, invalid, or improperly formatted details. If there are any, consider updating them and save your changes before proceeding to view/file 1099s.

If the issue persists, I would suggest contacting our Customer Care support to delve deeper into this issue. 

Once fixed, proceed with creating and filing 1099s with QuickBooks Online.

Don't hesitate to reply if you need further assistance with 1099. I'll be right here to help you.
