Thank you @DanaB27. I got a similar suggestion from @dmertz's response on the other thread: https://ttlc.intuit.com/community/retirement/discussion/re-backdoor-roth-with-rechar-and-conversion-...
So looking at my current 2019 Form 8606, I see:
Line 1: $6000
Line 2: $0
Line 3: $6000
Line 14: $6000
And this tax return was also filed through my same turbotax account and it has the $6K amount I assumed turbo will pick it up automatically. But let me try to go through your steps to amend my 2019 return first.
