It isn't the kind of experience that we want you to come across, ericpchao01.
I do appreciate you for sharing with us the steps to resolve the issues with regards to payroll.
As for the export, I'd recommend reaching out to our Phone Support team so we can take a look at your file and investigate further why you're unable to export IIF file. You can reach out to them through this link: Contact QuickBooks Desktop support.
Keep us posted if there's anything that I can help with. Keep safe!
