How do I export a video onto Youtube?

I have clicked the export & share option and agreed for Premiere to access my account on YouTube but when I drag and drop the video from Premiere onto the YouTube page it keeps telling me "Upload failed: Can't process file". I have Googled how tos, but most of them are either out of date or very vague on the specifics needed to get it to work. I played around with a couple different format options but after waiting around for the upload time half a dozen times just to get the same error, I have just about ran out of patience and have no clue what else to do. I'm sure it's a simple solution but I just can't seem to find it. Any information would be appreciated. I am using Adobe Premiere Elements 2018. Thanks.
