How can i speed up quickbooks, taking so long to upload

Hi there, @robin100. I'm here to help ensure you're QuickBooks Online (QBO) program will speed up. 

Intuit anticipates the most frequently visited pages in QBO to load in 10 seconds or less, and we constantly monitor our systems to make sure we're going to meet this goal.

Although the program is a web-based service, it is also reliant on your device's or computer's processing power, available memory (RAM), and Internet connection bandwidth. That said, let's make sure your system meets the minimum requirements to run QBO and ensure your operating system is up to date: System requirements for QuickBooks Online.

It is recommended to use Google Chrome to get the best experience possible. If you already using it, make sure this is updated to the latest release by going to the Chrome menu and clicking Help. Then, choose About Google Chrome.

Let's also verify your internet speed to determine that is not limiting your QBO navigation. To do so, run a Google Speed Test. For a better understanding of the results, please read over how the results are determined and what they mean.

On the other hand, you can also access your account via incognito mode to fix the uploading issue. If this works, go back to the regular browser and clear the cache. If not, you can use another supported browser as an alternative. 

I'm always here ready to lend a hand if you have any other concerns about accessing your QBO account. Have a good one and stay safe.
