Exactly how many e-files can I do in TurboTax Business?

Turbotax Business Download has a limit of 4 efiles correct?  At least on my computer, I was able to efile one 1065 and three state returns all under the same FEIN, but when I tried to efile one additional state return under that same FEIN, I got an error saying I'm past the limit.  But is the limit 4 efiles per FEIN or 4 total no matter if it's four 1065s or one 1065 and three state returns? In other words, can I efile three 1065s and three state returns, or would I be limited to efiling one 1065 and three state returns and I'd have to mail in the remaining two 1065s?
