va-4 form help. spouse works I just started working.

Hi yall,

I need help with va-4 form as I just started working recently.
I have been staying home with kids since last November and my wife has been working ever since.
Now, I am confused since I have only filled out W4s in the past..just fyi, last time when I was filling out forms like this, my company’s accountants just asked me few questions and filled it out for me, so I’m not so “educated”..and before that I was working and my wife stayed home with kids…so this is something new to us. Lol.

We have two kids.

Do I claim myself or not?

What is the line 4 would be then?

Thank you.
