I still can’t get it. How do I know I owe or I don’t pay enough? I have been using TurboTax to e-file and pay 100% returns for years on time and never got a penalty until now. Also, there is no explanation/calculation how/where the penalty came from. I received no letters/emails from IRS either. I think TurboTax needs to improve to inform users about the penalty while we are using the software since I didn’t know this until I reviewed the printing after I had e-filed. As such it’s too late to contact TurboTax to know how to eliminate it. Now, should I write to IRS or go see them at a local IRS office to get the answer?
