RSU's not reported on w2 and employer is refusing to correct. Is there a 'catch all' category where I can enter this income?

In previous years (when I worked for another department) my w2 gross pay adjustment calculation (to arrive at reported W2 wages) included a row for 'Plus STK Options'.  This is missing from my 2021 return and my employer is telling me to report the RSU's (paid gross) separately on my tax return.
