FY 2020:
I contributed $6000 after tax money to Traditional IRA in Dec 2020 and did back door Roth to Roth IRA in Jan 2021. Since the 1099-R balance still showing $6000 and for some reasons that I forgot turbo tax expert helped me to answer back door Roth questions.
Form 8606:
Box 1: 6000. Box 2: 16500. Box 3: 22500. Box 5: 22500 Box 13: 11000

My total non deductible IRA contributions are $22500 not Box 14 $11000 from previous year 8606. This is the issue.
