I made contributions to a non-deductible IRA of $28,000 and then converted this to a Roth IRA. The contributions were in a mutual funds portfolio and the increase in value was $3489 by the time of conversion. What is the taxable amount of this conversion?
Turbotax calculated $842 as non-taxable (I had considerable money in another traditional IRA) and $27,158 as taxable. I don't think this was correct, so how should I have entered the data into Turbotax?
