Turbo tax explanation of IRA recharacterization

[wendy3152020]

I read the Turbo Tax posted IRA recharacterization article (from the Turbo Tax Pop-up attachment). Is it still up-to-date? Page 11 of Page 15, "On the IRA Contributions Worksheet, enter the $4,000 original contribution to the Roth IRA on line 21". line 21, it is not for contributions (but for K-1). Also, what is the Form 1099-R replica? Can anyone help? thank you.
