Thanks for being part of the QuickBooks Community, Ipmg.
Allow me to share additional information about submitting an amended DE-9 form.
Currently, the payroll program will no longer allow you to submit a form that is already electronically filed. You’ll have to print and manually submit the DE 9ADJ form directly to the state. To get a copy of the amended return, visit your state website.
I've attached an article that will guide you on how to process the year-end's taxes and forms: Year-End Center.
If there's anything else that I can help find in QuickBooks, reach out to me directly by mentioning my name. I'll get back to assist you further. Enjoy your day.
