How to file additional filing requirement forms 8804;8805;8813?

After filling form 1065, I received a IRS notification asking for additional filing requirement forms 8804;8805;8813 due the partnership has foreign partners. I prepared the forms manually, the question is how to file?  can I send only those forms separately via mail to IRS or should I amend my e-file in turbotaxes by attaching the missing forms?
