Make too much to claim deductions...help

So we are married and file jointly. Last year we made say $160,000. Maxes out the 401k, student loans, mortgage interest, 2 children, and still ended up owing. It says we make too much money to claim the full credit for every deduction. How can we get more deductions or lower our rate? Make too much to get anything for a Roth IRA, maxed out our HSA. Any ideas?
