I only got one seed frase, I'm sure its right. It was printed on a paper, then carefully rewritten on metal plates. And I remember it.
I'm sure I was able to restore the wallet.
I doubt I'm that dumb to add an extended seed and fully rely on my memory with nothing on my metal plates.
I remember I was trying to create a seed that could be restored in other wallets than electrum. I remember I was clicking (*)Native segwit or smth in Electrum. There is a chance it was generated outside electrum. But I think I settled for electrum seed frase. I even could modify derivation path (very low probability). But I somehow restored it easily.
BTC are still there, I'm 100% sure the adress is mine. I still got a transaction from Trust to that adress in history. Also my keyboard layout could be LatinAmerican at that moment (I tried it, no difference).
