Get your taxes done using TurboTax

That's a great suggestion, theoretically.  However, the reason so many people have recently asked this question is that there is a bug in the online version (using Premium, having upgraded from Deluxe), which means that the 1040-ES is not being offered anywhere.  Indeed, the current UI bears no resemblance to this rosy picture being painted, of the form being available (as it used to be) under Other Tax Situations.  You're not missing anything; it's just not there.  Could someone from TurboTax (does anyone monitor these forums?) please fix this bug as soon as possible?
