How do i enter the months lived with taxpayer in u.s., on the minnesota information worksheet?

In  TurboTax Online, I am able to update the dependent's months on the Minnesota Information Worksheet when I change dependent information under My Info and Personal Info Summary.  Click Edit to the right of the dependent' s name.

Answer the question Did the dependent live with you the whole year?

If you are not seeing the correct months displayed on the Minnesota Information Worksheet, has the software given you credit on the Federal 1040 for the child as a dependent?  Have you been given credit on the Federal 1040 for the Child Tax Credit or the Earned Income Credit?

Consider deleting the dependent and re-entering the information.  To do that, click the trashcan to the right of the dependent's name on the screen Personal info summary.
