Retirement tax questions

If I choose Continue and leave that question blank, it's followed with:
Did you convert a traditional IRA to a Roth IRA before 2025? - Yes

What years did you convert a traditional IRA to a Roth IRA? - Answered: '2020 and Prior Years'
Report net conversions to your Roth IRAs that were taxable and nontaxable in 2020  - 
Again, another question which I have no answer for.

Note: I see another person facing this same issue and they were told to enter the full distribution amount or more into the box after "What were your Roth IRA contributions prior to 2025?"
