After you file

@Winton58  If you filled out your W-4 for the employer incorrectly last year and did not have enough tax withheld , there is nothing to be done about that now.   You have to enter your W-2 just as it appears; if you did not have enough tax withheld your 2022 refund or tax due is now going to be affected by that.  Going forward, you can complete a new W-4 for your employer and have more withheld for tax year 2023.
