Thank you for reaching out to the QuickBooks Community, MarcelleW.
The instructions in this thread are listed for QuickBooks Desktop. QuickBooks Online has a different approach, which involves creating a bad debt expense account, bad debt item, credit memo, and then applying the credit memo to the invoice. The article below will highlight all the steps associated with it.
Let me know if you need clarification for any of the steps! I will be here to guide you. I hope you have a great day.
