I'm glad you reached out here in the QuickBooks Community. Opening your account and finding no data would really throw a wrench in your day. Don't worry. I've got your back. QuickBooks Self-Employed is a cloud-based program, and your data saves on the server. The problem may be the way you're trying to access it. Let me guide you through some basic internet browser troubleshooting.
Follow these steps to eliminate your browser as causing the issue:
If you've been using the app, delete the app and re-install and try signing in again. Be sure that your user ID is correct. There's a chance that you may have inadvertently created a second account.
If you're still experiencing the issue, I recommend contacting QuickBooks Self-Employed support. This version of QuickBooks doesn't have telephone support, so you'll need to reach out through the chat.
To contact the designated QuickBooks Self-Employed team:
Select Assistant from the top bar.
Type and enter Talk to human.
Follow the prompts.
If you have any other questions that I can help you with, let me know. Take care.
