Taxes done wrong.

Hey.

 

I'm here on an H2B visa. This is my 2nd time filing my taxes but failed to file all documents I needed. 

 

I only noticed when I received the other paper work a week later. 

I've been trying to fix it on the App but it's not allowing me to upload and update the paperwork. 

 

How do I go about fixing this? 

 

Thank you in advance.
