I have same issue--anybody know the resolution?  thanks

Yes having the same issues, personal efiling has opened now, I have successfully efiled some myself, but Texas continues to have this issue.

We are also having this error.  Lacerte said to check again tomorrow.

This article https://proconnect.intuit.com/community/electronic-filing/help/lacerte-e-file-agency-approval-and-st... lists 2020 Lacerte e-file agency approval and start dates.  

As of now, this article shows Texas S-Corp 'Date available' as 'To be determined'

I am experiencing the exact same issue. Everything is good with the return. No critical issues, but getting this error: [etxcode=Go-Live,start=,end=04-30-2021 06:00 AM]
Problem occurred transmitting efile data.

Please reply if anyone has a solution to this problem.
