Oregon underpayment penalty being calculated even though amount due is less than $1,000 threshold

[debingeb]

My husband and I are retired and pay quarterly estimated taxes to the state of Oregon (and IRS).  This year we owe a small amount of additional state tax (approximately $100) and Turbo Tax Deluxe is calculating a penalty.  When I look at the instructions for Oregon Form 10, it clearly states that if the amount owed is less than $1,000 there is no penalty.  Why is Turbo Tax charging this penalty?  How can I get it removed before I efile?

If you overpay a penalty due to TurboTax BUG, Oregon should refund that penalty to you when your return is processed.

ovverride and file a paper return via US Mail.
