Were you required to report, as required by Section 457A, any nonqualified deferred compensation on your 2020 federal return? does anyone know what this question means?

[khardingmd]

I transferred my 457b to a roth 457 in 2020.

Yes.  Plans of deferred compensation described in IRC section 457 are available for certain state and local governments and non-governmental entities tax exempt under IRC Section 501.

They can be either eligible plans under IRC 457(b) or ineligible plans under IRC 457(f). Plans eligible under 457(b) allow employees of sponsoring organizations to defer income taxation on retirement savings into future years. Ineligible plans may trigger different tax treatment under IRC 457(f).

A governmental 457(b) plan may be amended to allow designated Roth contributions and in-plan rollovers to designated Roth accounts.
