Hey, @ambertree13.
It's great to see you back in the Community. I hope your day is going well. I can point you in the right direction so that you can change the State Unemployment tax rate for 2021.
I see that you create a thread in the Community with the same question. My colleague did provide you with the best answer so that you can edit this information. Here's the link to the thread so you won't have any confusion.
You can also check out our tutorials page to help you navigate and use other features in your QuickBooks Online (QBO) account.
