Thanks for the feedback.
actually the point is that the Government has approved the Roth SEP.
In fact, Turbo Tax has a place to be able calculate how much you can contribute to a Roth SEP based upon 1099 NEC
Unfortunately, no institution can take the money because the IRS has not given them the reporting.
So what is the work around solution
Although the change to the tax code makes it possible for SEP plans to offer the option for the contributions to be Roth contributions, SEP plans are not required to offer the option. Unless the SEP plan agreement offers the option, a Roth SEP contribution is not permitted to be made.
Correction: If the SEP plan is established using Form 5305-SEP, the employer can offer Roth SEP contributions before Form 5305-SEP is updated
