I'll provide some other options so you'll be able to change your company information, JS.

Normally, QuickBooks Online (QBO) has the ability or feature to let you change company data if you have the required user role. You can log out from your QBO account and log back in to see if you still can't make any changes to your company data. 

Aside from that, you'll also have to consider that when uploading a logo, it should be a .gif, .bmp, .png, .jpg, .jpe, or .jpeg file smaller than 10 MB24-bits or less in bit depth (or colour depth)square-shaped since rectangles don’t work using the standard RGB colour space.

In the same manner, you can convert it into an RGB image using tools (such as Adobe Photoshop) before you upload it to QuickBooks Online if your logo is CMKY-formatted make sure it is successful.
