You should seek local legal counsel and a local tax professional if you are uncertain of how to proceed.
However, it appears as if the state requires an annual report (which is rather typical).

With respect to filing the state equivalent of a federal Form 1065, that might not be required by the state since the LLC is a single-member LLC, but you should check with a local tax professional (peruse the information at the link below in the interim).
