Not a confirmation, but I would be very surprised if a TP could not e file multiple SMLLCs.

But you're asking about 1 from the entire Individual Module.  I know for a fact, because I had several SMLLC clients in each of the last four years, that you can e file multiple SMLLCs from the Individual Module.

I think you don't understand the previous firm's experience.
