No if you didn't submit it then it wasn't filed. You will know for sure when you file the Joint return. If you had filed by yourself then Joint will reject. And you can't file Single if you are married. Did you mean Married filing Separately? Yes Joint is the best way to file. Just abandon and leave your account. Don't use it anymore. Did you pay for the Joint return yet? You could file the Joint from your paid account. But you would have to enter all your husband's info to it.
