Clergy Housing Exclusion

I am an ordained clergy member of the United Methodist Church.

I am employed part-time and received a W2 with my income indicated in box 1.

I do not have a housing allowance as part of my income.

However, I do have a designated housing exclusion for tax purposes.  The income indicated in box 1 does not reflect this housing exclusion.  I entered my qualifying expenses in the W2 input process; however, there was no adjustment to my Federal Refund amount.  In the prior year's this is what I did and there was an adjustment.  How do I enter the housing exclusion properly?  Thank you in advance.
