When will the federal forms that are supposed to be available today go live for e-filers?

[MichaelDC]

Most forms should be available by end of day January 18. However, the IRS will begin accepting e-file returns on January 29, 2018. (A few returns will be processed up to a week before this date for testing purposes.)

If you file your return in TurboTax before January 29, we'll hold your return and submit it at that time.

Note: If your return is among those that the IRS processes early as part of its testing, your tax refund (if any) won't be processed until after January 29.
