In reading my blocker may be a terraform version issue. But I also got parts of the accounts setup going through the cold-start documentation… So I am going to do a lot more research to see if I should continue down the path outlined in cold-start or back out and use the reference-architecture design.

@Joe Hosteny Thanks for the link it did get me unstuck and I made a lot of progress! Unfortunately, I just bumped into another issue and am digging into it now

terraform init

Initializing the backend...

Successfully configured the backend "s3"! Terraform will automatically
use this backend unless the backend configuration changes.

Initializing provider plugins...
- Checking for available provider plugins on <https://releases.hashicorp.com>...
- Downloading plugin for provider "aws" (2.70.0)...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

* provider.aws: version = "~> 2.70"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
