Filing? Yes https://lfs.intuit.com/#/s/LA/F

My system is up dated to the latest version.  When I try to e-file the return, diagnostics states the LA Form IT-541 return cannot be e-filed at this time.  Lacerte systems specialist says Lacerte cannot e-file LA Form IT-541 but probably will be able to in the future.  I believe the system specialist is right since I cannot get passed the e-file validation process.  

I don't doubt that what Lacerte has posted is incorrect. I don't doubt that you had a negative experience in regards to LA Fiduciary return. My last one filed was in 2018 and it could not be efiled. "In the future" could mean maybe next year, as it appears that e-file is mandated for 2020 tax returns. If you have more than 10 K-1s I guess you have a problem for 2019.
