Why do I need to file Form 8606T if I've already submitted Form 1099-R for my Roth IRA distribution? I have no other 8606T situations.

Form 8606 is a form to report nondeductible IRAs and other IRA-related transactions that the government needs to track.  Examples include: 

• Distributions from a Roth IRA (especially to calculate the taxable amount of a nonqualified Roth IRA distribution.)
• Distributions from a traditional, SEP or SIMPLE IRA at any time after you have made nondeductible IRA contributions
• Convert a traditional, SEP or SIMPLE IRA into a Roth IRA

If you feel that the form does not apply to your situation, you can delete it from your return, using these steps:

"Distributions from a Roth IRA (especially to calculate the taxable amount of a nonqualified Roth IRA distribution.)"

More accurately, the only Roth IRA distributions reported on Form 8606 are nonqualified Roth IRA distributions and qualified first-time homebuyer distributions.  Regular qualified Roth IRA distributions are never reported on Form 8606.

In this case you apparently have received a nonqualified distribution required to be reported on Form 8606 Part III to determine the taxable amount, even if the taxable amount ends up being zero.
