How does my daughters boyfriend claim her since she lived with him

[Opus 17]

The boyfriend can only claim your daughter as a dependent if she lived as a member of his household for the entire year, and he provided more than 50% of her financial support, and her taxable income is less than $4300. If all this is true, he would list her in Turbotax as a person he supports financially, and answer the interview questions.

The Dependent type would be "Other."
