I have a 1099-R showing the entire amount of the distribution as taxable, and the "taxable amount not determined" box checked. I later indicated that all of it was a Roth conversion. None of it shows as taxable income.
Problem is that a small amount was gains while in the tIRA before the conversion. How do I get the software to show that amount as taxable? Can I uncheck Box 2b and put the correct taxable amount in Box 2a, or do I need to report the 1099-R exactly as issued?
