Dependents can only be claimed for the whole year, not for any period of time less than a year. In your case, visits from your daughter don't count as living with you.  Once your home ceased to be her primary residence, she no longer lived with you.  You can say she lived with you for 6 months.

If your child was over the age of 18 and was not a full-time student for 5 months out of the year, she cannot be your dependent if she made more than $4,050 during the year.  If she made less than that and you provided more than 50% of her support for the year, you can claim her by answering that she lived with you for 6 months.  She will not qualify you for credits though.

If she was aged 19-23 and was a full-time student for 5 months, then her income would not matter.
