Maximizing Roth individual (solo) 401K contribution

For 2023, I want to maximize my ROTH individual 401k contribution (and not contribute at all to my regular individual 401k). Is the maximized contribution to a ROTH individual 401k the same amount as what the maximized contribution to a regular 401k would have been? (In other words, can I have TT calculate the maximized individual 401k contribution then go back, put zero for the 401k contribution and put that amount instead in the Roth 401k contribution box? I have read that there has been changes to the roth 401k accounts for 2023 so i'd like to double check. Thanks in advance.
