Hello there, @amber201. Let's perform some troubleshooting steps and let your new employees do the same so both of you can get past the error encountered while entering withholding information or accessing pay stubs and other features in QuickBooks Online Payroll (QBOP).

You can either invite your new employees to enter their own W-4 info, or you can enter it yourself in QBOP. When you've encountered the error Something's not quite right, this can be caused by corrupted or damaged webpage data due to the browser's collection of files over time from frequent page visits. 

To get past the error, can pull up your QuickBooks Online (QBO) account using a private browser (incognito). Here's how:

• Press Ctrl + Shift + N (Google Chrome)
• Ctrl + Shift + P (Firefox)
• Control + Option + P (Safari)

Once signed in, go ahead and enter your new employees' W-4 info or let them accept your invitation and set up their QuickBooks Workforce account.

If you and your employees didn't encounter any errors, return to the default browser and clear its cache. This will refresh the system and remove older data that causes viewing and performance issues. However, if this matter continues, I'd recommend using other supported browsers.

In case the error persists after performing the troubleshooting steps above, I encourage you to reach out to our Payroll Care team. They investigate the cause of the error and guide you with a fix. To do this, here's how:

1. Sign in to your QBO company.
2. Go to the Help (?) menu.
3. Select the Search tab.
4. Click the Contact Us button.
5. Enter a brief description of your concern in the What can we help you with? field.
6. Select Continue.
7. Choose a way to connect with us (Send a message or Get a callback). 

Then, there are several payroll reports you can use to view useful information about your business' finances and employees in QBOP. If you wish to see the complete list and guide to access and customize them, please see this article: Run payroll reports in QuickBooks Online Payroll.

Also, you may want to share this article with your employees as their reference in case they need a guide in viewing their paychecks, W-2s, and personal info in QuickBooks Workforce: View your paychecks and W-2s in QuickBooks Workforce.
