W4 Form

I was required to complete a W4 for my new job.  It was my first time filling out the W4 form and I'm unsure if I filled it out correctly.  I elected 1 for Single. How can I make future elections to increase my take-home pay? How do I update it so I don’t owe 2023 taxes next year? What does it mean if my employer asks me to update my W4? @HollyP
