If you applied for TPS and you have the receipt from USCIS - I think you will be in status even if your H1b gets revoked. But if your TPS get denied and your h1b is revoked as well, then you will be out of status from the day your h1b gets revoked. This is what I believe but ask an immigration lawyer. I will advice you to find a consultancy who will transfer your h1b without any project.
