Hi! Was my IRS 10% penalty part of my tax return? I had an early 401k withdrawal and was expecting to pay in a lot, but still ended up getting a refund. Thanks!

Turbotax shows a pretty large estimated balance due for next tax season.  I've never seen that before.  That's why I'm concerned this estimated amount for next season has something to do with that 10% penalty.  But, I'd rather make sure the penalty is paid now.  I can't figure out if I paid the penalty or not.  I did report the early withdrawals and submitted the 1099R's on my taxes.
