Do I still have to pay penalty and interest?

[ytwiggy]

Found mistake on two prior years returns, that result in taxes owed on both. Because I found the error, do I still have to pay penalty and interest when I file these amendments?

State is Connecticut.

Thanks

TurboTax offers a 100% Calculation Guarantee.  

This means if you pay an IRS or state penalty or interest because of a TurboTax calculation error, we'll pay you the penalty and interest.

Thanks for your reply Karen, only the mistake is mine.  I am a retired teacher from a co-state/private institution.  my pension is paid by the state, and therefore I believed I qualified for the CT Teachers Retirement credit.  But apparently I don't because that is a different retirement system.

If there is a penalty and interest due to the state, you will get a letter from them asking for payment.  Until that time, just submit the corrected returns and pay the additional tax.  Perhaps they will be lenient since you corrected the error on your own.
