I'll help you log in, H2Q2.

Let's ensure you're using the correct credentials. Then, you can export your QuickBooks Online data to Desktop.

Although, if there's still no data, I'd suggest reaching out to our customer care support. This way, an agent can investigate this further. Here's how:

1. Click Help inside QuickBooks Online.
2. Select Contact Us.
3. Enter "No data when logging in" in the description field, then click Let's talk.
4. Select either Start messaging or Get a callback.

If you have other concerns, you're always welcome to post in the Community.
