1099-B for UTMA withdrew to pay tuition, does this need to be entered?

Maybe.  There is no exemption from tax for sales/withdrawals from UTMA accounts.  However, the income is reported on the beneficial owner's tax return (typically, the student) as it is considered to be the asset of the minor.  

Simple answer: yes.  Withdrawals from a UTMA are nor exempt from tax just because the money was used for tuition.

This is why 529 plans have replaced UTMA as the main savings vehicle for college.
