If I need to amend my W2 form to add another one but it’s down in the turbo tax app so I can’t, What do I do now?

last year, I had two jobs so I received two different W-2 forms. I didn’t receive the second one until I already submitted my first W-2 form in which was already accepted so I needed to amend it so I can add my other W-2, but it’s down in the turbo tax app which is where I filed my taxes on
