Hey CariD22,
Thanks for turning to the QuickBooks Community for support. Getting your users access to QuickBooks is important for us. I would be happy to provide some information.
Here is an article that shows you the steps on how to add users. If you have done these steps and are still having the same issues, I recommend reaching out to the support team outside of the Community. They'll be able to verify your account details in a secure setting, as well as view your screen to see why your users cannot access the account. You can reach them using the methods in this link.
If you have any other questions, feel free to reach out here.
