Let me guide you on how you can upload the W-4 form, integratedtherap.
You can go to the Internal Revenue Service (IRS) page and upload the new form. Just go to this link to access it: https://www.irs.gov/newsroom/faqs-on-the-2020-form-w-4.
Then, go to Where can I download the new Form W-4? section and click the About Form W-4, Employee's Withholding Certificate link.
To enter and print the W-4 in QuickBooks Online (QBO), just follow the steps and details in this article: What’s changing with the Federal W-4?.
I've got a link here that provides you articles about managing employee's payroll: Payroll and workers.
I'm just one post away if you need a hand with running payroll transactions or any QBO related. I'm always here to help.
