So, you created a wallet with a mnemonic passphrase without really knowing how it works (or vague understanding)?

You can learn more how HD wallets work here: https://learnmeabitcoin.com/technical/keys/hd-wallets/mnemonic-seed/ or from the start of it https://learnmeabitcoin.com/technical/keys/hd-wallets/.

As you can't afford to loose any part of your mnemonic recovery words and your mnemonic passphrase, make sure you have secure redundant backups.

I would also recommend to verify if you actually can restore your HD wallet successfully. Do this only in a secure environment, never expose your mnemonic recovery words to an online device which security status you don't know or can't safely assess. Do not make digital pictures of your mnemonic recovery words and/or your mnemonic passphrase. Digital pictures are commonly synced to some cloud and cloud providers often abuse their picture content to "improve" their AI shit. You lost control of your secrets the second they got synced to some cloud storage unless it is completely your own cloud hosted on devices only you own and operate.
