I'm encountering the same issue with e-filing TX Franchise Tax as of 3/4/21. The error prompts, "You cannot e-file this tax return because the Intuit Electronic Filing Center is not open for the season yet. We accept 2020 Texas Corporation tax returns from beginning of tax season to end of tax season. We'll see you then! "
Based on this message, Intuit office is not open and the tax season has not started yet?
