If you started an LLC by yourself, then your best choice would be to file Sch. C on your regular tax return.
That would be the cheapest and simplest way. If you have other partners, you will need to file a partnership tax return.
Unless of course you chose to be taxed as a corporation. In that case, you will need to file corporate tax returns. that is rare though and it's only done if you have a specific reason.
Now, with regards to state, in general, if you operate out of one state, then you will need to register there but not sure what exactly you've done or you still need help with any of this.
