I've had three 1040 clients this week tell me that they got a refund check for the underpayment penalty that was calculated on their 2023 return in ProConnect Tax.  The underpayment penalty calculations for all three of these clients appear to be correct to me (i.e. there's no reason they would be exempt from the penealty).  Is anyone else experiencing this?  Am I missing something?  Is there a glitch in the 2210 calculations in ProConnect?
