Retirement tax questions

Thanks, but my question was about splitting my contributions between my solo regular 401K and my solo ROTH 401K.  (In other words, I have a solo 401k account that has a regular tax-deferred part, and a Roth 401K part).

 

Based on a net profit of $40330, a SE Tax of 5698 and the fact I'm over 50 (and have no other earned revenue) could I make the following contributions ?

Regular 401K :  Elective Deferral of $5150

ROTH 401K : Elective Deferral of $17850  (=$23K minus $5150) and Catch-up contribution of $7240 - this would be a total of $25,090 to my solo ROTH 401K

Thanks
