How to use touchscreen Laptop on Adobe Photoshop?

I just bought a Lenovo Flex 2 and I want use my adobe CC for touch example you use brushes to draw.

Probably should have asked around first, because many touchscreens can't be used this way. Photoshop may only allow you to pan/zoom/rotate the canvas with the touchscreen, and require other input devices for actual painting.

Some tablets/laptops can make use of a pressure-sensitive stylus in a manner similar to graphics tablets. You may want to ask around the Lenovo forums whether the Flex 2 has this capability.
