As of today, ProSeries Professional client letters, OK individual 2020 2nd quarter estimated tax due date trigger code is pulling an incorrect date of 7.15.2020.  Per OTC website, OSCPA & AICPA covid 19 sites Oklahoma has NOT moved the 2nd quarter due date from 6.15.2020 to 7.15.2020 yet.  I called tech support today to ask for the authoritative source for ProSeries change (sometime between 5.7.2020 & 5.14.2020). They did not have any. Heads up to all with Oklahoma individuals with 2020 estimates, you'll need to manually fix the letter until ProSeries fixes.
