ProSeries will not re-program to accomodate the later date..  never did.. why is a different question but taxpayer can pay at irs.gov

Spoke to Pro Series and they said to uncheck the box that says "enable conversion error checking" and the return will be submitted.  Just submitted one that way to test it; IRS rejected it.  Intuit did not give accurate guidance.

Why hasn't ProSeries made the appropriate adjustment for this?

Intuit didn't do it for (virtually) the entire State of CA  two (three?) years ago.

They don't consider it 'necessary'.

Theyre not going to reprogram for the convenience of a few states. 

In the time it took to complain about it and call in you could have scheduled the payment using IRS DirectPay, done!

Hi @DJNC 1. See "Can I delay the withdrawal of tax due when I e-file the return?" from Disaster area tax extensions.
