How do I reverse trades? Do I need to write into Steam Support?

First, make sure you're in control of your Steam account. If you need help regaining control, or aren't sure whether someone else has access to your account, please contact Steam Support directly.

You can review the list of your trades containing Trade Protected items, and begin the process of reversing them, directly from your Trade History page.

A direct link to your trades eligible for reversal can be found here.
