The transactions shows it has 5 confirmations but the total doesn’t reflect on my btc balance
That btc is lost huh? :/
I still have a hard time following what has happened... But yes, if a transaction that should have funded your address has 5 confirmations, but we see no transaction funding said address on a block explorer... Yes, the odds are pretty big that the btc is lost...
So, if i understand correctly, you have an app called "cash app", we have no idear what this app is or where it came from, but it is funded.
You created one transaction by creating an address with electrum and scanning the electrum QR code with your "cash app". The transaction was created, confirmed, and you see in electrum that the address has been funded. We did not get any info about this transaction tough
You created a second transaction by creating a new address with electrum and scanning the QR code with your "cash app", the value of the output should have been 0.006, the address you created with electrum was bc1q6l8pjwa50df2dg0qe0fm62akygzz85a8y976jc and "cash app" is telling you the withdrawal txid is b73015303dc7803d969d5dce99f3d1dfe178832704c5b0b21c5180671a85a74f. We verified said transaction, and the only output created by this transaction with a value of 0.006 is funding address bc1q53aw7vuytll255mrglzyk0grlrrw8japyfgzaq. NeuroticFish gave you a way to verify if bc1q53aw7vuytll255mrglzyk0grlrrw8japyfgzaq belongs to your wallet, but you haven't given any feedback about this
You created a thirth transaction, but haven't given any extra info.
Could you do the following things? Most of them were asked before, but you didn't answer them yet...
Could you execute NeuroticFish's command on the electrum cli?
Did you verify electrum? Where did you download it from?
Could you give us any information about this "cash app"?
