Here is an article that is on topic: How do I prepare a joint federal return and separate state returns?
To summarize, to file a joint federal return and separate state returns in TurboTax, use the Desktop version and follow these steps:
- Ensure your state allows separate filing if you filed a joint federal return.
- Prepare and file your actual Married Filing Jointly (MFJ) return with the IRS.
- For the 1st Spouse: Save a copy of your joint return, change the status to "Married Filing Separately," and delete the other spouse's income/deductions. Use this to generate and mail the first state return.
- For the 2nd Spouse: Start a new "mock" file from scratch as "Married Filing Separately" with only their data. Use this to generate and mail the second state return.
Important: Only file the one joint federal return and the two separate state returns. Never file the "mock" federal returns used to create the state paperwork.
