Called customer support and Information Return System does not support IRIS yet. No timeline of when they will be. We have to move the information from return system file as text to the csv file and then fill in remaining fields to upload correctly to the IRIS system (or manually enter each one). We are new to e-file, but I work IT. This is the only workaround at this time. However, if you are registered with FIRE than you can still upload there. Our office was not.
