Now i understand you have feature file and step definition file. But not able to navigate to the step definition when clicked on test in a cucumber feature file

Is it because you font have a plugin installed?

To install plugin here is the step.

Go to File -> Settings -> Plugins

Find cucumber for Java, if you are using java (or)

find cucumber for Scala, if you are using Scala

Then install the plugin. That’s it! Allow some time. You should be able to navigate to your step definition
