How does claiming my daughter work?

We have a son together and my daughter (his step daughter, hates the word step)

My husband is the only one that has worked all year

we are filing married jointly 

how does claiming my daughter work? Is she just a regular dependent that goes under child tax credit or does she go under Other dependent? 

He contributes to more then half of her expenses 

I am the custodial parent

We have her for more then half the year

she is 7 

I need help with this cant get in contact with IRS to ask( to high call volume)

need to fill out his W4 form asap

also does it make a difference that we got married in June?  

All help is very much appreciated, I am going crazy trying to figure this out
