My online version doesn't have a find button so i can do CRA autofill

The Find tool is located in the top right-hand corner. It may look like a magnifying glass if you are using a smaller screen.

You can also get to the Auto-Fill page by choosing "Auto-Fill My Return" from the left side menu. On a smaller screen, you may need to click on the 3 lines in the top left to see the menu.

If you start a new tax return, the tool is visible only after you have completed at least the Intro and Profile steps
