401K MRD to Roth COnversion

Approximate numbers --- I took an $80K as my 401K distribution, but was then advised by my broker that moving the $80 to a Roth Account was a better idea. He moved the money within the specified period, opening a Roth for me. My 1099-R now shows a distribution of $180K with taxes withheld of $20K. TurboTax now shows I owe roughly $40K additional taxes on this total distribution.

How do I show that $80K of the $180K was moved to the Roth Account as I don’t see where to enter it in the 1099-R section of the form
