How to access Free File for prior year tax returns

How do I access my Free File account in order to access prior year tax returns? I recently lost everything due to a fire and need copies of previous year returns but Turbo Tax no longer participates in the Free File program so how do I access my prior year tax returns? I tried to reach support ten ways from Tuesday but they seem to be mythical creatures that only exist in a phantasy land that doesn't really exist. I just need access to my account.
