Had both a 401k and an independent 401k this year. contributed max elective deferrals to the regular 401k. How do I enter $6000 I contributed as "employer contributions?

I have maxed out an employer sponsored 401k at 18,500.  Later in the year I worked as an independent contracted and started an independent 401k.  I contributed $6k as the employer.  It seems TT only allows me to enter these contributions as "matching contributions"  They weren't matched to anything.  How can I use TT to determine how much I can contribute as an employer to the i401k and how can I properly enter these figures?
