Personal exemptions were removed from the tax code after tax year 2017 so are not on a W-4.

Go to this IRS website for a tax withholding estimator - https://www.irs.gov/individuals/tax-withholding-estimator

There are no allowances on a federal W-4 - https://www.irs.gov/pub/irs-pdf/fw4.pdf

Is this for a state income tax withholding?  If so, what state?

No, it is federal taxes. State Florida. 

The taxes deductions of my bi-weekly check. 

I just want to know what is the best number to deduct from my check 

i just want to create a balance of the taxes deductions and my monthly incomes

The best way to find out how much tax needs to be withheld per pay period, so that you owe no taxes at the end of the tax year, is to use the IRS tax withholding estimator.
