Your HR department is correct in that the withholding tables for Married Filing Joint Return will be less than the withholding for Single or Married Filing Separately. Assuming you have no other income than your W2 wages, you have a couple of options. You can update your W4 and select the "Single" or "Married Filing Separately" filing status to increase the amount withheld. You can also leave the filing status as "Married Filing Joint" but indicate an additional amount to withhold on Line 4c.
If you had a balance of tax due with your 2022 tax return, you can divide the balance due with that return by the remaining pay periods in 2023 to have that amount withheld by the end of the year.
Be sure to change your W-4 again in 2024 to reflect the correct amount per pay period going forward.
