1040X with Foreign Wife Income

[Allison33]

I'm trying to make a tax amendment for 2023. I just got married December last year and when doing taxes last February I accidentally filed as single and instead of married. I'm trying to fix it and want to file jointly. My wife is from the Philippines. How do I add my wife's foreign income on TurboTax amendment form? And should I include her Foreign Income Tax Return as evidence when filing? I'm also adding form W-7 for her.
