It's quite curious that this option isn't allowed for TurboTax Desktop, as explained here due to IRS restrictions for form 4868, and yet efiling of extensions is allowed for TurboTax Online via TurboTax Easy Extension.? (see https://turbotax.intuit.com/irs-tax-extensions/ … FYI, Normally available beginning mid-March. Can use for free, though do need to re-enter all of the estimated amounts)
C'est la vie?
