nonqualified ROTH vs non

I'm 60 and retired.  I've had a E*Trade ROTH for 10 yrs.  In my company 401K I've converted some fund to the ROTH side.  I would like to move the ROTH funds to the E*Trade ROTH but they say it is unqualified for 3 or 4 yrs depending on when the conversion was done.  Well, the 3 yrs was after tax funds 4 years for conversion.  

I will be doing more conversion to a desired amount before RMDs happen.  

Are any new conversion qualified after the 4 yr time frame?

Why can't I move the funds to my fund to a qualified ROTH?
