I made nondeductible contributions to my traditional IRA from 2007 to 2019. This year I received my first IRA distribution and in calculating my nondeductible contribution total basis, I discovered that Turbotax failed to carry over my total basis from previous years (IRS Form 8606, line 14) to line 2 of the current year. It did file Form 8606 for each year and included the correct nondeductible contribution amount for each year, but according to Turbotax, my final total basis is only what I contributed in 2019. Based on my records, I can calculate my final total basis, but it differs significantly from what Turbotax filed for me in past years. Should I enter the correct total basis amount on my return?
