Wait
In first post you said you transfer FROM kraken to you LEDGER
If this is true, in “widthdraw” kraken page, you should have put your public address (the one that start with G)
So you should put the same address (I repeat, the one that start with G) ito a chain explorer (like steexp or stellarchain)
And furthermore, you don’t ever need you private/secret key (the one that started with S) to check your Wallet history
