I need to enter the 10% penalty for taking an early withdrawal from my traditional IRA but TurboTax Premier won't let me enter just the penalty. I don't have additional tax to pay because I've lost income in the IRA per my cost basis.

I need to enter the 10% penalty for taking an early withdrawal from my traditional IRA but TurboTax Premier won't let me enter just the penalty. I don't have additional tax to pay because I've lost income in the IRA per my cost basis. Can TurboTax pleased fix this?  I overrode Form 5329 to include the penalty but now I can't eFile.
