Sorry to see you are having this problem. We can certainly guide you back to edit your T4. Once inside your return, you will click on the Find (magnifying glass) icon at the top right of the screen. From there, please follow the steps as seen in the image below.

The T4 Summary screen will open, as seen in the image below. This is where you will be able to click Edit to change the T4 information as needed.

Thank you for using TurboTax.
