turbotax easy extension complains "we are currently not accepting filings of this type"

[rhyu]

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.

It is too soon.  The online easy extension usually becomes avaiable around mid-March.
