I double checked:
The total basis as of Dec, 31, 2019, I put down $6000, as shown on my 8606 form last year (2019).
The next screen value of traditional IRA as of Dec, 31, 2020, I put down $5.56 (because I made a conversion from traditional IRA to roth IRA with the $6000 during 2020, so there is little leftover money).
My question is: the contribution to traditional IRA is after-tax and nondeductible, why I am taxed a second time just converting it to Roth IRA?
