Filing married joint, does both spouses file their taxes in their own turbo tax account? (submit twice)

Hello, I am in the process of filing married joint for this year taxes. But I was wondering, does my husband have to file on his own turbo tax account as well for this year tax return? Or does me filing in married joint taxes causes both of our tax return be processed in at the same time, therefore my husband does not need to do anything else on his end (he does not need to file under his turbo tax account) ?
