Can a married couple file MFJ in seperate states? If not, can they still file MFJ federal?

We worked in different states than each other last year so I think we have to file in those different states. Am I wrong? Will we be able to file with the IRS jointly? Isn't that the best for higher returns? I want to claim moving expenses and opening- up-a-new business expenses and donations by itemizing, but my husband doesn't have anything to itemize. Would it be better to file seperately this year? He for sure owes and I for sure have money coming to me. We have an appointment in the morning and I don't know what to do. Thanks for any advice.
