Terraform plan - how to see the autoscale max size setting

I have an AWS beanstalk where I defined the autoscale max size on the console beanstalk configuration in the instance traffic and scaling section. I then did a terraform plan - I am looking for the correct terraform setting from the beanstalk so that I can set up my other beanstalks as well as update the terraform script for future needs. My problem - I cannot find in the terraform plan where this parameter is defined so I cannot figure out where, or how, to define it in my .tf file.

I found the settings for min size and max size - these appear to be for auto scaling. Now I am looking for
min_size = 1
max_size = 2

I still need the scaling trigger fields
