Traditional 457(b) to Roth 457(b) conversion

How to I reflect some traditional 457(b) funds were converted to a Roth 457(b)?  TurboTax asks:

"Is this 1099-R reporting a rollover of funds from a 401(k), 403(b), or governmental 457(b) plan to a designated Roth 401(k) or Roth 403(b)?"

However, it never asks if it was rolled over into a Roth 457(b).  Thanks.
