I've checked our file and didn't see any reported cases same as yours, Diane74.
This is probably a web cache issue. To start with, let's open QuickBooks Online using an incognito window to isolate this. From there, try to run your payroll. If you're able to do so, go back to your main browser, then clear the cache. Too much cache can affect the system's performance. Having said that, it's better to clear it every now and then.
Moreover, using a different browser fixes issues like this (Google Chrome, Internet Explorer, or Mozilla Firefox).
Once you're done doing the steps, try to run the payroll.
Feel free to let us know if you have more questions. We'd be pleased to answer them.
