That link gave me a CSV file. My client was on the CSV but the Name was longer than what Lacerte allowed, so thought it was a mismatch. Other replies are saying that should not matter. I tried submission again and found when I moused over the "US Failed Transmission" message under "Activity":

"The program did not successfully transmit the tax filing. The filing failed pre-submission validation. Validation Failure: Error 854: Your E-fling privaleges (sic) have been temporarily disabled by Lacerte. Please verify the 1 EFIN number associated to your account at LacerteAccountants.com/EFIN-Facts"

However, I get "This site can't be reached" when I try going to LacerteAccountants.com so, another dead-end.
