If you are filing as Married Filing Separately you need to enter your spouse's name and Social Security number. This is the only information needed for your spouse.
If you filed as Married Filing Jointly using the 2022 TurboTax online editions and you are using the same User ID to start the 2023 return, then you need to create a new account and User ID if you are not going to file as Married Filing Jointly on the 2023 return.
