I was able to download the latest update this afternoon (about 9 hours ago) and complete my e-file successfully at that time.
Ironically, at 10pm this evening, I received an email from Intuit with the subject:
"We’re still working on Form 7206 not supported for Efile in Desktop"
The message read:
"Thank you for being patient while we investigate your issue. Rest assured, we're working tirelessly on a solution and will email you when we have more information. Thank you for being a TurboTax customer."
😁
