Although I have estimated my tax and paid by 4/15, I still owe some tax that I plan to pay soon. But I am not sure if the number turbo tax provides include the interests or not. How can I tell?

Any penalty calculated on your return would not include interest since interest depends on the length of time before you pay your tax liability.
