I'm a bit confused here.
In 2015 I converted an old 401(k) account with ~$6k in it into my ROTH account held by Vanguard.
I did this because I had no taxable income for 2015 and wanted to use my automatic deduction "head-room" to convert some of my tIRA into a ROTH.
Vanguard handled the entire transaction. Now I have a 1099-R from my former 401(k) (TIAA CREF) and I can see on Vanguard's website that it was an "Employee Rollover Conversion" with no tax withholding. Besides my normal 1099-DIV there's mention of the rollover in my "tax center"
Q: Am I missing some form(s) here? The 1099-R lists everything as a "Gross Distribution (box 1)" and the entire amount is taxable (box2a). I understand I owe taxes (at least in the sense that I'll use my standard deduction to 'cancel-out' the $6,000 conversion) but I don't want to pay a penalty since the money was automatically converted and rolled over into a ROTH IRA (i.e. I never recieved a distribution - it went from TIAA to Vanguard).
