Unable to create storage account

I have just started learning Terraform. And I stuck. In Azure Cloud with the help of command I was trying to create a resource group and storage account. But the name I gave for resource group is not unique. Hence, it failed . Now I am unable to run with a new name since subscription id and tenant id are already used. Is there any way to delete those from directory?

You can delete the object from your state file: Command: state rm | Terraform by HashiCorp

Deleted the directory by this command -del .tf
Then change the storage account name and try to do create Storage account and Resource group using terraform command, but now getting this error-
