I'm using TurboTax Online version and trying to file an extension through 'TurboTax easy extension' through below steps:
"Tax Tools" -> Tools
click "File an extension"
then, the browser jumped to easy-extension
then this is what I got (tried on different browsers and machines, the same thing):
It looks like this filing is not available
We are currently not accepting filings of this type.
When you select Sign out, we'll sign you out of your TurboTax account.
