ckappenman2,
TurboTax does address your situation in https://turbotax.intuit.com/tax-tips/marriage/doma-tax-implications-for-same-sex-couples/L1LDCicXw which says:
Even though same-sex marriages have been nationally recognized since 2015, some couples may still be in a domestic partnership or civil union rather than a marriage. For federal tax purposes, individuals in a civil union, domestic partnership or similar formal legal relationship are not considered married under state law. This prevents them from filing as a married couple at the federal level. If legally married at the state level, married couples should consider their options before choosing to file as married filing jointly vs. separately.
So what it tells us is that you simply file as a Single taxpayer based on your own income alone and your partner does the same. Two individual returns. (If you live in a community property state, you would generally split your household income in half instead of using each of your incomes separately.)
