Hey there @GleasonFan - thanks for using Dropbox and welcome to our Community.
If the upload is still stuck could you send us a screenshot of how it looks on your end so that we can have a visual too?
With this amount of data, I'd suggest uploading your files in batches as the web browser you're using might crash or time-out with such a large upload.
In any case, please let me know of any updates!
