How do I apply my disability exemption to my 1099-r from my ira?

I took a withdrawal from my IRA. I am permanently and totally disabled. Fidelity withheld the 10% penalty and marked my 1099-R with no known exemptions even though I told them I was P&T. Turbo tax never asks about any exemptions. How do I add my P&T disabled exemption onto my Turbo Tax to show I don't/didn't owe that 10% penalty?
