TurboTax bug for 8606? I did backdoor roth (from trad ira to roth conversion) for 2020. It left everything blank for part I and put a few numbers in part II. I'm lost!

1. contributed 7000 Trad IRA
2. converted to Roth right away with just 7000.02 balance
3. received 1099R
4. entered in TurboTax, TurboTax gives these on 8606 form
part I: all blank (no numbers filled)
Part II:
16: 7,000
17: 0
18: 7,000
It seems wrong that nothing is on Part I.  When I manually fill, I will have the numbers for Part I.
