how to enable route propagation in the routing tables

I hope all is well. I am working on a project to move our infrastructure to terraform and have the Infrastructure as Code. Route propagation is not working in our test account however I copied everything that we have in our main account. I know there is no limitation for routings and it should be a technical config issue. 3 VPCs (Prod, Dev, Stage) are going to route traffic to the internet through 1 VPC (DMZ) and 1 IGW in the DMZ. In the main account the routing is working fine but in the test account the propagation does not change to enabled ("yes").
