RE: 2101
No worries on your questions...this is a huge learning experience for all of us.
Basically, you will execute HRBENUS_ACA_XML for your RunID
This will create the XML file(s) that you will upload to the IRS. This includes all the data for the 1095-C forms. If you look at the XML generated, you can see all the employee details in the 1094C_Request. You will also see data that resembles the 1094-C information.
Once you get to the point of actually uploading files to the IRS, you will find this is probably the most simple part of this entire process. Having said that, I have no idea how the 'correction' process will work. Then, things might be tricky.
