Why when I enter an after tax Ira contribution from form 5498 does my refund go down?

[dmertz · Accepted solution]

Until you enter your year-end value in traditional IRAs, TurboTax assumes that the year-end value is zero, resulting in an incorrectly high amount for the nontaxable portion of your traditional IRA distributions and Roth conversions.  Once you provide the correct year-end value, TurboTax can do the correct calculation on Form 8606 Part I.
