FWIW, I called Lacerte yesterday, 1/9/2019, about a FY2017 January 15 due date e-file that was not sent to the IRS.  The gentleman told me it will be sent to the IRS on January 16, 2019.  The January 8 date is not accurate as a reopen date anymore.
Additional info***My e-file was sent and received by the IRS today, 1/10/2019.
