Will TurboTax not allow me to change (Arkansas) state filing status to Married Filing Separately?

I got far enough while preparing with TT to see that I would save more money filing separately, although I am married. However, after I got to the Review section, I was notified that I could not e-file for Arkansas because Federal was set to Married Filing Separately, while State was set to Married Filing Jointly. I saw no way to change State status to Married Filing Separately as desired. How do I do this?
