Since 2014, I have been making nondeductible contributions to traditional IRA (5500 each year), and immediately converting to Roth IRA (backdoor rollover). I made my contribution for 2016 in early 2017 and converted it to Roth, so the balance in my traditional IRA is $0. However, for form 8606, is my total basis $16500 in traditional IRA as they were all nondeductible contributions? Or is it $0 since all the fund have been converted to Roth IRA shortly after contribution? How do I manually edit Form 8606 as Turbotax doesn't seem to be reflecting the changes I made? My total basis should be $16500 but TurboTax has it at $11000.
