None of the versions of TurboTax support Form 8594, and Form 8594 does not seem to be a "stand alone" form that can be mailed in separately, nor is it a Form expressly mentioned on Form 8453 - "U.S. Individual Income Tax Transmittal for an IRS e-file Return."
Play it safe and mail your income tax return this year with Form 8594 attached.
