Yes, it can be non-taxable, but should have been set up before taking the distribution since it has to be direct from the IRA to the charity. I use Schwab & fill out a form prior to the transfer, naming the charity, address where they are to send the check, and the amount.
In Lacerte, go to Pensions/IRA, etc. and at the site scroll down to "charitable IRA distribution" where you check a box & enter the amount. The amoun will be deducted from the IRA distribution with a a statement "QCD"
