How can I print the "CRA received your NETFILE return" without getting all the info on the left side in the gray border?

I edited your question to remove personal information.

Unfortunately, there is no way to remove the left side bar through TurboTax. However there are a couple things you can you try:

-          Copy & paste the confirmation info into Microsoft Word (or any other word processing software) and print it there.

-          Use screen capture software to take an image of only the confirmation info part of the screen. Print out the image.

You can also check your email – the confirmation number will be there too!
