You can use the actual online ROS form 11.
Open the prepopulated form 11, play around in any way you choose.
Don't sign and submitt.
You can close and reopen the form 11 as many times as you want.
When you are finished playing with the form 11.
Exit the form.
Go back to submit a form online.
Select... income tax...form 11
On the next screen select delete the form 11. The form 11 will then revert to it's original prepopulated state as sent by revenue.
You can repeat this process as many times as you like.
You can let the form 11 calculate and you can print out the calculated results.
You can also do this after you have signed and submitted the form 11. When you choose to edit an already submitted form 11 you need to click a box to change the form. Choose correct an error.
Again you can play around but don't sign and submitt.
When you then delete the form 11, it will now revert to your actual submitted form 11. Nothing has changed. Your signed and submitted tax return remains as was.
You can do this for previous years submitted form 11 returns.
I have done all this many times.
This is a great way to learn how the form 11 operates.
