Colorado state tax penalty
On our 2023 Colorado state income taxes, we paid in all but $1230 because we got a sales tax refund of $1600. We were supposed to get an overpayment refund of $370. We ended up only getting $291 back. Evidently, we had a $79 penalty. We prepared our 2023 State and Federal returns with turbotax and it never showed us being charged a penalty. The state offered no explanation to us as to why they kept the $79. Can you tell us why this happened and possibly what we did wrong when turbotax said that we were 100% free of errors?
