I've obscured your email address from public view but have checked that the address is valid and the mailbox is active. So you should not have an issue receiving mail to the Inbox, subject to the current incident that's being worked on by the Mail platform operator.
I would recommend checking via TalkTalk Mail webmail that there are no Rules in play that might be diverting mail from your Inbox. So, when the incident is shown as resolved:
Select here: Sign in to TalkTalk Mail
Enter your full TalkTalk Mail email address, select Continue and enter the password, select Sign in.
Via the main Settings cog icon top right, select the All settings menu item and in the left pane select Mail and scroll down to Rules. Delete all rules that are there to make sure nothing is stopping mail from arriving in your Inbox.
If you need to lock out all other devices that might be downloading mail and deleting from the Inbox then select Security in the left pane and select Sign out all devices and then recheck the self send of mail to see that mail does arrive in the Inbox.
If you happen not to recognise any Rules or signed in devices then scan your email devices for password capturing virus or malware and upgrade the mailbox password.
