Oh, I'm not asking you to paste it here. And, no, the tx does not expose the private key, by design (otherwise, you would be giving away your private key to the peer nodes when you broadcast the transaction). Good on you for not assuming, however.
Here's a link describing the tx format. I recommend extracting the inputs from the tx using Core commands. This way, you're not trying to manually monkey around with the bytes. You can safely post the addresses of the
inputs because an address is just a public record index in the blockchain that is associated with an unspent output. Once you've confirmed whether the inputs are still funded, then it's a matter of trying to resubmit the transaction.
To check any address or transaction ID for yourself, just go to
blockexplorer, copy-paste it in and then press enter.
Addresses, block numbers and transaction ID's are always 100% safe to show to others. You should exercise care with public keys - while they will not compromise your funds if they are exposed, exposing them is equivalent to
address-reuse which is discouraged on the basis of long-term security considerations. Of course, showing your private keys is equivalent to giving away cash, so take utmost care with them ... just avoid handling them as much as possible beyond the minimum required to make sure you control your funds and have proper backups, etc. And, yes, you have to specifically
export your private key in order to expose it (please don't do this, even locally). This is why this usage is discouraged. Instead, people are encouraged to "sweep" private keys, which just submits a transaction moving your old coins to a new address with a fresh private key.
When you have some spare time, consider reading over
this amazing blog post to demystify the mechanics of Bitcoin transactions. Even if you're not a techie, just skim over it to get an idea of what's involved. Think of it kind of like looking under the hood of a running car ... even if you don't understand all the whirling gears & levers, you still get a feel for what's going on inside the vehicle.
If you decide to re-broadcast the transaction, you can use
this page unless you have Core, then there's probably a way to do it from there.
Hope you get your coins back!
