spot healing tool

You may follow these steps: https://helpx.adobe.com/in/photoshop/kb/bringing-back-tools.html

In Photoshop go to Edit>Toolbar and click Restore Defaults, then Done

If your Photoshop Spot Healing tool isn't visible, you likely need to either click and hold on the Patch Tool icon in the toolbar to reveal the hidden Spot Healing Brush option or check if your toolbar is set to display all tools; you can also try resetting your workspace to defaults to ensure all tools are visible again.

Did you post in the Illustrator forum by accident and your question is actually about Photoshop?
