W-4 for multiple jobs

Hello, I will have 4 jobs to report for taxes this year. One job between Jan-March and 3 new, part-time jobs that started in March. I may transition back down to 2 part-time jobs in the fall. I am having a hard time understanding how to update my W-4 to make sure enough taxes are being taken out. There's currently a low amount of federal tax being withheld on the paychecks, but I know I will need additional withholdings most likely. Is this the type of event where I can get support on that?
