The new form doesn't work like the old form. It has a total of 4 pages including instructions and worksheets, and you will need to file a new W-4 at all your jobs. If you want your withholding to be correct without giving the IRS an interest-free loan for the year, read and follow all the instructions and worksheets, using either the 2-earner worksheet or checking the box at 2c.
The IRS has a web site where you can check your withholding, but it's down for "maintenance" (probably to reprogram for 2022). After getting a couple new paychecks under the new W-4, try using the IRS site to double-check.
