Hi @Scarletk_FL,
I'd be glad to add some information about the UID. You'll need to open your .qbo file in a text editor or a Notepad to change it. You can check the steps on how to do it in the thread below. Just scroll down to @Haole Boy's post.

Once done, you can try re-importing your file again.
I'm also attaching these articles for additional reference:
In case you need help with other QBO tasks, browse this link here and select a topic that suits your needs.
Keep me posted if you still have questions or concerns about the program. I'll be around for you. Take care and stay safe.
