Hi Nancy111,
Thank you for your post and welcome to the MYOB Community Forum. I hope you find plenty of useful information.
We’re sorry to know that your super payments have been returned. Currently, we don’t have an option to delete those completed transactions at the pay super payment window. We suggest reversing and reprocessing the super payment. This helpful article returned superannuation contributions has all the detailed information and steps to assist you with this.
Do let us know if you need further help.
Cheers,
Shella
