Last year I rolled over my roth 401K from previous company to Vanguard roth IRA, and received 1099R, on that tax form it shows about 1/3 of the money is my contribution, yet after I import the form, my tax due went up a lot , and on the `Retirement Income Results` page, it showed all the gross distribution from box 1 is taxable, that's is so not true, my contribution part is after tax money, and any dividends earned from my portion should be tax free too, why do I have to pay tax on the whole gross distribution? is there a way I can correct this?
