When you have completed your 1094, click on the Ok and Save menu option.  This option saves any changes, but also gives you an opportunity to process this group of 1094 and 1095's.   If you are ready to transmit, click OK and if you are filing indirect, you can send the returns to Lewis Software for processing at a per return fee.  If you are a direct filer, it will create the manifest and form files that you need to upload to the ACA AIR system.
