Ok, I will not panic. Thank you! But I will be looking into this more once I finish my work 😅

In Trezor software they call this a "hidden wallet" and to access it with the device plugged in you enter the 25th word as a passphrase... If you restore a wallet you use the 24 words and think of the 25th as another wallet connected to the existing 24 words. Most wallets will ask you if you have a 25th word, you enter it after the 25 word and your in. This is the question of over-security can actually make you less secure. Some people who are worried about wrench attacks find this helpful as they can give up some coin and have rest hidden behind that word...
