My now husband entered the wrong filing status for 2019 tax returns

I got married in 2020, so I filed my 2019 taxes as single. But my husband (as of 2020) accidentally filed as "married filing separately" even though we weren't married in 2019. I tried e-filing and it was rejected saying that my husband already claimed me as a dependent - even though he did file separately - but married. Now how can I complete my tax returns. Should I put "married filing separately" even though we weren't married last year?
