I explained this to you when you asked a few days ago.
There should be a * next to line 15 on the8606 that means the calculations were done on the "Taxable IRA Distribution Worksheet" and not the 8606. View that worksheet to see how line 13 was arrived at.
Line 13 is the non taxable part.
If you converted the entire Traditional IRA to a Roth so tat no Traditional IRA existed at the end of 2020 then line 14 should be zero and the taxable amount would be the total 1099-R box 1 minus $12,000.
Line 14 suggests that you entered a non zero 2020 year end value that would be in the above mentioned worksheet line 4.
