Can I use the toys that I donated to a family in need for christmas as a charity donation?

Sorry, no.  To be deductible, donations must be to a tax-exempt organization, not a specific person.

(One way to make this deductible is if your church had announced "we are accepting gifts for a needy family", and gifts were donated to the church, and you did not have control or influence over which needy family the church chose to bless in that way.)

Unfortunately, gifts to individuals are not deductible. Only qualified organizations are eligible to receive tax deductible contributions.
