QuickBooks Online (QBO) doesn't support the filing of amended or corrected forms, which means you'll need to handle them manually outside of QBO, @rmsuez.
I highly suggest contacting our Payroll Live Support Team if you need to file an amended return. Here's how:
- Go to the Help icon in the top right-hand corner.
- You can use the QB Assistant by entering your question or topic, or select Search, open an article, and then press the Contact Us button.
- Select a topic or enter your question in the box and hit Continue.
- On the "How would you like to connect with us?" page, choose either Have us call you or Chat with us.

To learn about their available hours, please visit this article: Get help with QuickBooks products and services.
Alternatively, connect with them directly through this website. Simply choose your QBO product, then select Continue.
On the other hand, you can check out the list of payroll reports you can use in this link: Reports available in QuickBooks Online Payroll.
If you have any follow-up questions or concerns regarding filing an amended 941 in QuickBooks, don't hesitate to use this thread.
