Where to update skills content in Lambda Console?

My name is Mike and I seek help. 
Our family has created several Alexa skills - all the same type… ask “alexa, ask <skill name>” and she uses a random number to get a random line from a text file in lambda and then speaks the response.

Our skills are listed at - http://vanvooren.us/Alexa/VanVooren_Alexa_Skills.html.

I want to update some of the things in the text file that Alexa reads from… and I have no clue where to go any more.

I remember logging into the Lambda Console (https://us-east-1.console.aws.amazon.com/console/home?nc2=h_ct&region=us-east-1&src=header-signin#?) and seeing a list of our skills, and I’d click one and I could edit the text.

Do you know where I need to go to edit the text files in the lambda console - where to log in? where to click after we log in?

Thanks, Mike
