I am having same problem.  Two clients with large estimated tax payments were not taken out on 4/15.  Also balance dues are scheduled for 5/17 so I am nervous about that.  Have called Intuit and they say they are aware - they also said call IRS which I am on hold right now for 1/2 hour so far....Intuit should be all over this.  I understand Lacerte having same problem.  BillG
