Hi MI1918,
Thanks for posting in the Community!
As of the moment, we don't have an option to lodge BAS via mobile app. To be able to lodge your BAS and access your GST/BAS reports, please login to your account via web browser.
If you would like this feature to be requested for future updates in QuickBooks Online, I recommend you to send feedback to our Product Team by going to the Gear icon and select Feedback.
For your reference, please check this article: Lodge your BAS or IAS in QuickBooks Online.
Feel free to drop a comment below if you need further assistance. Have a great day!
