You need to upload with NOTHING connected to the board , the blink sketch, using a USB lead .
You should be selecting UNO as your board , not anything else , then show us the result , the displayed messages on the computer screen .
Make sure you have verify set in the options .
It’s the only way we can be sure what’s happening and give advice. ( we don’t have your display or it’s connections , so remove everything , that’s everything)
