Assign the textfield an instance name and use a condtional to test if the length property of the textfield is not zero.

if(yourTextFieldName.length > 0){
// do whatever
}

Only you can answer that. Put it wherever you need to check the textfield. Ideally, if you are coding in the timeline, all code should be in the main timeline.
