I appreciate you letting us know about this, @SusanT3,
All payroll forms in QuickBooks are accessible under the Payroll Tax menu. If the page is unresponsive or will not launch the option to view state returns, try opening your account in a private browser.
Sometimes, the data in the cache can cause unexpected issues in QuickBooks Online. To launch a private window, use any of the following keyboard shortcuts:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Safari: press Command + Shift + N
Once logged in, follow these steps:
Go back the the Payroll Tax tab and click Quarterly Forms link.
The next window will show a list of forms you can pull up.
Click the form you need and choose View.
If you're able to successfully pull up these reports in the incognito browser, go back to the regular window and clear its cache. This will help remove the piled data on the history, so you can start with a clean slate.
Let me know what you find after trying out the steps. I'll be right here if you need further assistance with payroll or anything in QuickBooks. Have a nice day!
