Thanks for chiming in, everyone. It's seeming more to me like I have made an error by contributing to a Roth IRA. I'll have to get this sorted out with Vanguard :(
We're talking very small amounts of income here: total, I probably make $35,000 a year between both income sources :S In fact, my camming target was a clean $5,500 for the Roth limit, but I suppose all that doesn't matter now! I'll exclude camming income along with teaching income on 2555, pay self-employment taxes, and just throw my moneys in a taxable account instead of Roth.
Again, thanks so much. I realize I do have a complicated situation, and I couldn't bring myself to pay an international CPA $300 to answer questions in a half-hour session. I think I sort of knew the answer, but didn't want to face the reality that I made an error months ago haha!
