How can I link to the account that was created for me by my org?

I signed up but was not connected to my organization which granted me access to certain folders and forms. I cannot figure out how to set up my account so it's linked directly to REST. Please help!!

What is your account username where you were granted access to the forms? If you do not have access to the account, what you can do is to sign up for your own account, then ask the owner of the main account to grant you access to his forms as shown on this guide: How to Share Forms with a Sub-Account User.
