SharePoint List disappears in OneDrive

Hi,

I can't find any information about this online, so I'm hoping someone on here can help. I created an Excel file "HOLIDAYS" and saved it to my OneDrive/SharePoint. I tried to use that file in Power Query, but quickly discovered that the easiest way to retrieve that one file in Power Query would be if it was a SharePoint List instead of Excel file. Therefore, I converted the Excel file to a SharePoint List and it promptly disappeared from OneDrive/SharePoint. I can see the file in Power Query, however. But since I am unable to find and edit the file in OneDrive or SharePoint it is useless to me? I will eventually need to add the holidays for next year, so I need to be able to find and edit the file. Any help would be greatly appreciated!
