Amended return from overseas

Hi, sent my amended return off for 2024 last month, was delivered on July 21. Been checking my online account for amended returns, have seen nothing... Now I'm worried I didn't include enough info. I just put the return and my w2 for that year. My social security number, I assume, is linked to my online account.

How long does it take for this to be updated or for them to acknowledge the receipt?
