I am a Colorado resident and e-filed my state taxes. I use the Annualized Installment method (Colorado Form 204) so I don't pay a penalty for underpayment. TurboTax does not include this form, so I was hit with a penalty this year. I note that another correspondent in Massachusetts had exactly the same problem with her/his state tax return. So I'm done paying their $25 e-file fee for an erroneous filing. Time to get this fixed, TurboTax!
