So I went to calculate late payment and interest for a client who will have a large balance due on a 1040.   The Penalties and interest form has 4/18/22 for the due date.  Doing a search of the community on this topic and it seems every year for at least the last 2 years, this has occurred.  But never this late in the season. 

Really Proseries???   I have been a loyal user since 2003, but the stuff that is just not right is starting to get really old.
