Please Help With My TikTok Account Recovery

I am a TikTok user in the United States and I am having a serious problem recovering my main account. The display name of the account I am trying to recover is “yourfamous***” and the username is “red.ise***”. I lost access to this account on or around February 12, approximately two months ago, and since then I have not been able to log back in. I do not remember the email address or the password linked to this account. I tried to use my phone number, but it is already linked to another TikTok account, so it only shows me my other accounts instead of the one I am trying to recover. While trying to solve this, I have even rediscovered older TikTok accounts under my name that I had forgotten about, but none of these are the account I actually want. I have already contacted TikTok support and followed all of the basic instructions given to me, including using my phone number, email address, password recovery, and the account recovery option. However, the recovery option only shows the accounts I already have access to and never shows the “red.ise***” account that I am trying to find. At this point, the standard recovery tools are not working for my situation. My main request is to recover access to my account through a manual, identity-based process. I am willing to verify my identity by showing my face or answering personal questions related to the account and its content. If possible, I would also appreciate help with deleting some of the extra accounts under my name, but my priority is to do whatever is necessary to regain access to my main account. I kindly ask TikTok to review my case in detail and provide a manual solution so that I can access my account again.
