Cannot get the trial balance printing out the figures for the correct period even when I put the correct period in

You got me here to share some insights about how the report period works on the reports in QuickBooks Online, MI441. 

The Trial Balance populates from the selected month in the settings. The report will only run from the first of the month entered, so in your example, we will have to set it by April. Here's how:

1. Go to the Gear Icon and then select account and settings. 
2. Click the Advanced tab and then in the accounting section edit the First month of the fiscal year. 
3. Hit Save and Done.  

Know that each report in the system has a different default period. To view the details your desired transactions, we need to manually select the date range from the drop-down menu. To do this, here's how:

1. Go to the Reports tab.
2. In the search field, type in Trial Balance.
3. Then, click on the drop-down arrow in the Report period, or modify the date range.
4. Click Run Report.

If we want to view the desired transactions and display it by months. Here's how:

1. Go to the Reports tab.
2. In the search field, type in Trial Balance.
3. Then, click on the drop-down arrow in the Report period, or modify the date range.
4. Select Months from the Display columns by drop-down.
5. Click Run Report.

We can also export the report in Excel to make the necessary changes in the report. I'll guide you how:

1. Go to the Reports menu.
2. Type in Trial Balance in the search bar, then click to open.
3. Set the correct date range.
4. Select Months from the Display columns by drop-down arrow.
5. Click on the Run Report button.
6. Choose the Export drop-down arrow.
7. Select Export to Excel.

If the same thing happens, we can perform some basic troubleshooting steps to isolate the issue. At times, the accumulated cache in your browser causes odd behavior when running the financial reports. Let's start by accessing QuickBooks Online in a private or incognito window. Just refer to the shortcut keys I've listed below:

• Google Chrome: Ctrl + Shift + N
• Microsoft Edge: Ctrl + Shift + P
• Firefox: Ctrl + Shift + P
• Safari: Command + Shift + N

If you're able to view the trial balance data it without any issues, go back to your regular browser and then clear its cache and cookies to start over fresh. Alternatively, you can switch to other supported browsers.
