Hi there, CHouse1.

There is an ongoing product investigation about Unable to process employee's Super batch with SMSF due to a validation error "ABN didn't match and SMSF Details are mandatory for SMSF fund". I recommend getting in touch with our Customer Care Team and reference the investigation INV-117362 to discuss it with them and be added to the affected users. That way, you can receive email notifications or any updates.

To contact support, use this link https://quickbooks.intuit.com/learn-support/en-au/contact or click on the Help (?) in QBO and click on Contact Us.

Feel free to post again in the Community if you have other QBO questions. Have a great day!
