State tax filing

"multi-member LLC treated as a disregarded entity and taxed as a partnership"

This contradicts itself, if youre taxed as a partnership, youre not a disregarded entity.  When you applied for and obtained your federal EIN, the letter that was provided that showed the EIN would have also shown what tax form would be required and when it was due....do you have that letter?
