Retirement tax questions

No, no prior balance.  Only other transaction within the Traditional IRA was in 2020 with $6K moving and then back out to the Roth IRA.  No contribution in 2021.  And then the 2022 with $6K moving in and out to the Roth IRA.  I checked the account directly. 

 

The 8606 form (generated from Turbotax) shows 

Line 1:  $6K

Line 2: $6K (which should be 0)

Line 3:  $12K

Line 14:  $12K

 

And my CP2000 letter states underreported "Retirement Income Taxable" of $6K from Vanguard

 

So it seems that my 8606 is wrong (assuming I made an error while working through Turbotax), but then shouldn't I have overpaid if the 8606 is overstating my distribution?  

 

Do I just respond to the CP2000 with an updated 8606 form?
