Retirement tax questions

I received my form 1099-R from my IRA custodian.  I had directed that contributions of $2k each to my church and to a college be made directly from my RMD.  These contributions were made. I believe that these were QCDs.  My form 1099-R box 1 Gross Distribution shows $6085.15, my block 2a Taxable amount shows the SAME amount.  The block 4 is $417.03, the tax on the distribution balance after the QCDs at 20%.  How do I lower the block 2a Taxable amount, to show these QCDs??
