Hello, Alessia.
Thanks for the screenshot and taking the time to contact our support. I do have important details about the missing data on the Profit and Loss and Balance Sheet reports.
On your second screenshot, you've selected the All Balance Sheet Accounts filter. The Profit and Loss report won't show those balance sheet accounts, which is why you're not seeing any data at all.
The Profit and Loss report shows the expense and income accounts, so you'll want to select the All Income/Expense accounts filter instead. You can also choose a specific income or expense filter if you want to exclude an account from the report.
As for the Balance Sheet report, run it separately since it shows a different set of accounts (asset, liabilities and equity accounts).
If you want to filter specific accounts, select your assets, liabilities or equity accounts.
If you'd like to learn more about these two reports, I can recommend these articles:
After running the reports, do you also need to reconcile your books? Check this article if you need a guide: Reconcile an account in QuickBooks Online.
Do you want to learn more about other reports? Please let me know what you need to do and I'll help you out. If you have any other concerns about QuickBooks Online, I'll hear you out.
