What happens if you just ignore the diagnostic? Is it an e-file CRITICAL diagnostic?

What diagnostics will prevent a return from being e-filed?

E-file critical diagnostics and Fatal critical diagnostics will stop an e-file return from being e-filed. E-file critical diagnostics typically generate when Lacerte recognizes something that will cause an e-file reject. Make sure to resolve any e-file critical diagnostics and fatal critical diagnostics before continuing to e-file.  Additionally, some critical diagnostics that are not e-file critical diagnostics will stop the return from being e-filed.
