Hi Alexis,

Thanks for posting in the Community!

There's a Payment details field/box in the QuickBooks Self Employed invoicing page that you can enter your super details from there to show in your invoices. 

1. Click on Invoices tab.
2. Click on Create invoice.
3. Locate Payment details field.
4. Enter your payment details from there.
5. Click on Save.

However, know that we're unable to process super payments in the QuickBooks Self Employed accounts. I recommend directly processing your super payment to your clearing house or the ATO.

Check this link for reference on how to: Create invoices in QuickBooks Self Employed.

If you are using the QuickBooks Online version, you can refer to this link to learn more about processing super payments using Beam in QuickBooks Online. 

Feel free to reply to this post if you have other questions about QuickBooks Online.
