The new w4 form and having 3 jobs

Hey all, sorry for my smooth brain here but I was hoping to get a little direction. I am having a hard time understanding what the heck I have to do to fill out my w4 correctly.

– married
– filing jointly
– 1 dependent
– Married person 1:
– Job #1, full time $73,380 for 2021 salary ($9,194 YTD)
– Job #2, part time maaaybe $200 so far (new job)
– Married person 2:
– Job, full time $54,577 for 2021 salary (YTD unknown atm)

Appreciate any advise on how to properly have my forms filled out so I am not over/under withholding

Thank you!
