W4 form for employee tax withholding

New W4 forms don’t have a line for choosing how many exemptions you want to claim. It used to. It has spaces for multiple jobs and dependents, but not exemptions in general where you can choose how many you want, so you can gauge how much tax, if any, is withheld.
So if an employee does not have multiple jobs, is single, with no dependents, that’s enough for the employer to calculate how much to withhold?
