Turbotax Premier allows up to 12 returns to be filed - If I file a common-law couple, does that count as 2 out of the 12 returns?

Hello, 

I have the Turbotax Premier, and it says it allows up to 12 returns that I can file.

1) If I file a common-law couple (2 people who are common-law partners), does that count as 2 returns out of the 12 that I can file? or does it count as just 1?

2) Also as a premier user, can I netfile (e-file) up to 12 returns? 

Thank you.
