Again I figured it out it’s not bogus and if you do the following it will work go to

E-FILE

attach PDF files and click on that

When you will be taken to a stop menu where it tells you to attach a PDF file upload one go to word type up your ACA explanation and make sure you title it as such then upload it to that sub menu and then make sure you put the description in the description column, make sure you type ACA  explanation and then hit OK or whatever and it works and the return will get accepted

Took me a long time to figure it out but it finally worked!!!!!
