This year, I have problems creating MFS returns. they do not split.

You need to provide a little more info - what happens when you try?  Any error messages?

If you talking about taking a joint return and make it 2 separate returns I have been able to do them but they are REALLY weird.  A lot of forms with errors don't show up as errors until you go to the form.  Like ID Validation.
