So you have lived in two community property states, formed a husband-and-wife LLC in a third community property state that you never lived or worked in, using an agent's address, and now live in a common law state (i.e. not community property). I'm guessing that the LLC never engaged in any business activity in the state where it's registered. The husband-and-wife LLC filed for 2020 as a partnership, and you think you might have filed the partnership tax return with the wrong address. I strongly suggest that you visit a tax professional to straighten it all out, and to find out what your filing obligations are for 2021. When you meet with the tax pro, bring copies of the LLC formation documents or partnership agreement, the 2020 Form 1065 partnership return, and your 2020 personal Form 1040 tax return.
