Question About Form W-2/Box 16 /State Wages

I have a Form W-2: Box 1 Wages $20000,  in Box 12, it has a $1000 HSA contribution. but Box 16 state wages is $21,000 which means it already included that $1000 HSA.   when I enter this W-2 into Proconnect. I received a Critical diagnostic regarding HSA below:

Employer HSA contributions from the federal form W-2, box 12, code W are to be reported as an add-back on California Schedule CA-NR, Part II, line 1h, column C. The program did not automatically include employer HSA contributions as an add-back on Schedule CA-NR. Please enter the total employer HSA contributions from all the W-2s in "Other earned income [Adjust]" for an add-back on Schedule CA-NR, Part II, line 1h.

My question is:  this W-2 box 16 states wages already include that HSA $1000.  what should I do to clear this HSA related diagnostic?   I can't enter another $1000 by following the diagnostic instructions, because that will add the extra $1000 to CA income.

Thanks!
