Formula for 401k and ROTH

SOLVED

Good Morning,

I was wondering if anyone has a formula created for 401k and ROTH, I know the combined contribution between the two cannot exceed $19,500 in 2020 but I have employees who have both and the system has a limit on 401k of $19,500 and ROTH of $19,500 which is great for those only doing one or the other but for employees who have both that does not work.  Any suggestions?

I am fairly new to SAGE CRE300.
