Unable to log on the saas desktop

You are hosting your file on a 3rd party provider. You must contact their Support team directly. If they ignore you, consider switching to another provider immediately. Be sure to secure your backup files locally and frequently.

Welcome to the QuickBooks Community, @Liyd.

I appreciate you reaching out to us here in the Community. I'm happy to lend a hand.

 As Fiat Lux - ASIA's suggestion, I recommend reaching out to the SaaS Support team. This way, they can guide you through the process of transferring your data from QuickBooks Desktop.

Our Community forum is always open to help you again if you need further help with QuickBooks. Have a good one!
