Good afternoon, @gretchenv. 

Allow me to help and share some information about syncing your QuickBooks Desktop with QuickBooks Time. 

First, let's ensure of two pin points so that we can narrow down the cause of the error: 

• Sign in with the master admin credentials
• Make sure that the credentials you're using can get you logged into the accounts.intuit.com link. 

If these work and you're still experiencing the error, then you'll need to contact our support team. We'll need to see if you're a part of a particular investigation (INV-00254). Cruise on over to this guide to get a direct phone number or use the steps to start a chat: Contact QuickBooks Time support.  

I see you contacted support recently but don't see any details as to how that interaction went. Would you mind letting me know if they were able to solve your problem? I want to make sure this is taken care of for you. I'll be back around shortly!
