Good day, @FCL82. Thanks for your response.

For me to better identify the issue, can you share with me the region of QuickBooks Online you're currently using right now? This might be the reason why you're not having the same preferences. You can also add a screenshot for additional reference.

Please know that the Overview tab will only appear once you select the project that you've created. 

Any additional info would be much appreciated. I'll be here to help you further. Have a nice day.
