How do I prepare 5500s online so my client can submit thru EFast?

Although I've prepared 100's of 5500's in the past, that was when we used paper. I don't know how to complete a 5500 so my client can file on EFast.

I've subbed out 5500's to a CPA firm for years, but this new client does not want his 401(k) and PS Plans information shared outside of my office. I realize 5500s are public record anyway, but I want to honor the client's wishes. 

Where do I prepare his 5500's for him?

Thank you, and have a great day. 

Typically the admin software you use will have a 5500 module that you have to purchase. Seems like a lot of effort for a single client. 

It is a lot of effort, but I want to keep this client. I have been told I can prepare 5500s fo clients on the DOL site or EFast site. But, I cannot find that.

If you can log on at the DOL EFast site, you should be able to create 5500 filings.  I do it once a year for a client.

Thanks Bri and Bill. 
I think I see on the efast how to do it.

Thanks again.
