Your stated $24,500 of regular and catch-up elective deferrals is fine. Your stated $7,500 of employer contribution exceeds your maximum permissible employer contribution of $4,062 by $3,438.
I think what you are trying to do is say that you contributed only $4,062 of an employer contribution and that you made elective deferrals of $27,938. That's a bit iffy, particularly if you designated to the plan custodian that $24,500 was elective deferral and $7,500 was employer contribution as would be done with the custodian that I use for my individual 401(k). The election to defer a particular amount must be made by the end of the year for which the contribution is being made, and allowing yourself to elect a $27,938 deferral seems sketchy.
