I can help you manage your users, laurahorner3705.

I'd like to verify if you got an error message or the contact list is greyed out? It will help me walk you through the correct steps. In removing a user, let's ensure that you are the primary contact of your account. Then, you can follow the steps again shared by Ashley H.

If the same thing happens, it's possible that your browser may be full of frequently accessed page resources, thus causing unusual responses. To isolate this, you can try logging in to your Intuit Account using an incognito or a private browser. Then, select and remove the user from there, 

If it works, I recommend going back to your default browser and clear its cache. This process aims to speed up your overall browsing experience and removes the history or log of sites so you can start with a clean slate. If the issue persists, you can use another compatible browser.

However, if the same thing happens, I suggest reaching out to our Phone Support Team so they can seamlessly do it for you. MadelynC provided the detailed steps on how to get in touch with us. 

Please let me know how it goes or if I can be of additional assistance in the comment section. I'm only a few clicks away if you have any follow-up questions or concerns. Have a great rest of the day.
