You expected more than the software does. TurboTax desktop software has forms mode and a "what if" feature that lets you roughly compare MFJ to MFS, but it does not break it all down to little details, and it only splits things 50-50---which might not necessarily be the way you do things if you actually file MFS. So if you want detailed accurate results you go to the work of preparing the three returns--one MFJ, and two for MFS.
To use the WHAT IF tool:
- Click Forms Icon (upper right of screen) or Ctrl 2 (forms view)
- Click on the Open Form Icon
- In the “Type a form name.” area type What-If (with the dash), click on the name of the worksheet - click on Open Form
- You will see the worksheet on the right side of the screen; enter the information right into the form
- To get back to interview mode - click on the Step-by-Step Icon (upper right of screen) or Ctrl 1
