Yes, if you were legally married as of 12/31/2022, you can only file Married filing jointly or Married filing separately.
See What is my tax filing status (single, married, etc.)? for more information.
However, if you lived apart, and you paid more than half the cost of maintaining your home, and you provided care in your home for a qualifying person (usually your dependent) then you may have the option of filling head of household.
If you file married filing separately, you need to provide your spouse's name and SSN. If you don't have that information, you can't e-file. You need to print your return (you may need to use a fake SSN to pass Turbotax's error check), and attach a written statement explains you are separated, you don't know your spouse's SSN, and give whatever identifying info you do know (full name, birthdate, last known address).
If you are eligible to file HOH, you don't need your spouse's information.
