Generally the full QuickBooks online functionalities support desktops and laptops in a full browser capacity so if you are using your ipad, you have to use a browser preferably Google Chrome then logon to QuickBooks from there then to "Employees" for payroll and you should then be able to do this.
Please let us know if you require further assistance.
Thank you for posting. There are times when a browser's cache data becomes full of frequently accessed websites or damaged. This causes unusual behaviors in the QuickBooks system or program. I suggest logging into your QuickBooks account through a private browser. This will help us determine if the problem is related to the browser's settings. Start by using an incognito window.
If it works using the private browser, go back to your main browser and perform a clear cache to remove temporary internet files on your computer. Use these keyboard shortcuts based on the browser you're using.
Feel free to reach out again if you have any other questions.
You can access Employees tab on an iPad via browser like Safari or Google Chrome.
If you're encountering another login page on the Employees section, try and disable Prevent Cross-Site Tracking and Block All Cookies in Safari's settings:
Let me know if the above steps works well on your end. Have a nice day!
