According to Proseries (I was on the phone with them for 2 hours today) CA 540 payment due date was updated on 3/26/21 to accept the 5/17/21 date.  My system shows an error using that date. Is anyone able to use the 5/17/21 date?  Is it just my system that will not update? Is anyone able to file suing a 5/17 payment date?
