Hi LA33_3, great question! To know if your withholdings are set up correctly, you would have some idea when you filed your 2021 tax return and either you had enough withheld and received a tax refund, or you did not have enough withheld and had tax due.
If you had tax due, or did not file a 2021 tax return, you will want to revisit your Form W4. There is a W-4 Calculator that will walk you through the steps for your specific situation of filing status, income, dependents and more.

Once you complete the form, give it to your employer. Then, keep a close eye on your next few paychecks to see how the changes impacted your federal income tax withholding.
I hope you find this helpful!
