Empty folder in Trash on iPhone XR

I moved an empty folder to my iPhone XR Trash folder and now it won't delete. I've tried using the web version of Yahoo (yes Yahoo, I know, don't ask why please), but the delete option is grayed out. I can re-name it but that doesn't help either. When I tried to delete the folder initially, I received a message that it couldn't be deleted from the server. After several days of trying, I finally moved the Mailbox Location to the Trash folder thinking that it would be removed automatically at the end of 7 days. No such luck. Everything else gets deleted but this empty folder. Now I can't even change the Mailbox Location on it to move it out of the Trash folder.

My phone is up to date, as is my PC and both the Mail & Yahoo Mail apps. There's nothing in the folder, never has been, but I just can't get rid of it and it's bugging the heck out of me. I've tried using 3 different browsers as well, and still no luck.

Does anyone have any other suggestions I can try to get rid of this folder?

Thank you!
