How do I enter 2021 SIMPLE IRA contributions via a Partnership that do not show on Schedule K-1?

I am in a Partnership LLC and received a K-1.  We have a SIMPLE IRA plan and Line 13, Code R shows the contributions that occurred in 2020.  However, the company also made an additional matching contribution in calendar year 2021 AFTER the K-1 was issued.

How do I enter this additional contribution in TurboTax?

Do I simply fudge the 13-R number or is there somewhere else to enter this?

Thanks.
