Clergy Housing Allowance

I have a W-2 for my employment as a minister and all of my income on my W-2 was designated as housing allowance for my home.  I entered it in Box 14 as Clergy Housing Allowance, but it's not deducting the amount allowance from my taxable income.  TurboTax has articles that say that I'm supposed to enter the housing allowance as a negative number in "Other Reportable Income" but when I do that and attempt to file the IRS rejects the tax return because it thinks I made an error.  Can someone please tell me the correct way to deduct my clergy housing allowance from my taxable income?  Thank you!
