Hello andresdelosrios!
Congrats on our good problem!
The Turbo Tax W4 tax calculator tool can help you determine how to fill our your W4 https://turbotax.intuit.com/tax-tools/calculators/w4/
Once you fill out the information you can make adjustments for additional withholding if needed by using the slider. I've included a screenshot of what this looks like.
I hope this helps!
