Content

Customer is going live 1/1/2021 and would like to know if there is a way to upload 2020 and previous years' 1095c forms. The available document type 1095-C is configured as Publish required as Yes. Due to this, we are not able to load the documents to this document type.

If we make Publish required as No, then we are able to upload but once done, we are not able to set Publish required as Yes. Is there any other way to upload prior years' 1095-C
