I have an inherited Roth IRA which was created in 2010 by converting a traditional IRA just before I inherited it. The only distribution was the RMD I took in 2011. According to the IRS instructions I don't owe any tax, but I have to fill out form 8606 because I don't meet the 5 year rule. Unfortunately none of the tax software supports this (they have the form, but don't support the entries for inherited IRAs). It seems kind of silly to have to paper file just because I have to put a couple of numbers on a form resulting in a 0. Any ideas on how I can handle this and still e-file? What are the pitfalls if I left off the 8606 since it doesn't affect the amount of tax I owe?
