Get your taxes done using TurboTax

As you stated, that since less amount of tax is being withheld, you are now owing money for Federal Tax. The best approach for this would be to edit your Form W4 and increase the tax  withholding so that more amount is being withheld from each paycheck throughout the year, so that when you file taxes next year, you will not owe that much.

I have attached a section of Form W-4 and highlighted the relevant area. You can withhold extra from each paycheck by filling out that section through your payroll website and this way more taxes will be withheld from your paycheck but then you will owe less money or possibly get a refund when you file your taxes next year.
