California FTB Mandatory e-Pay with withholding

Hi, folks

 

Last year, I got a notice from FTB that I triggered the Mandatory e-Pay requirement for the future. And I checked the wave conditions and figured out I did not meet.

 

This year, I calculated my tax and realize that I did not own any state tax, my employer already withhold enough state tax for me, in fact, I will get refund from CA.

 

But the options in the site indicate that I have to pay something:

So I am confused what I should do with this situation.

 

Thanks for any advices
