Here is the FAQ from Lacerte:
Can I e-file Prior Year Business Returns?
You can e-file the current year and two prior years for Business returns (after the IRS opens e-file for the current tax season).

Business Filing Example: When the IRS opens the Business e-file servers for TY18 in early 2019, you will be able to e-file 2017 and 2016 Tax Returns. Once the IRS opens the Individual e-file servers for TY18, Lacerte will open both TY18 Business and Individual e-file.  If a return is submitted after its applicable due date, it will be considered late.  Once the IRS shuts down the MeF system in November 2019 for Individual returns, 2016 tax returns can no longer be transmitted.  

Looks like IRS will accept old returns starting yesterday but Lacerte is waiting until the 2018 year filing date. You would think that there would be a simple Lacerte switch to turn on to be able to e-file the business returns now....
