Definitely a noob to BTC
I purchased bitcoin, downloaded Bitcoin Core, and sent the bitcoin to the Core wallet. I then realized that it was going to take multiple days for the "Synchronizing with network" to finish, so I created a private key using the address I had sent the bitcoin to. I then opened Electra, which I have used before, went to Wallet>Private keys>Sweep and entered the private key, and pressed "Sweep". A window then popped up showing the correct value of BTC that I was attempting to transfer, and I was given a new address, that now shows up under "Used" under the "Addresses" tab in Electrum with 0. under "Balance " and 0 under "Tx".
Here's where I think I did something wrong: I was following an online guide that was using an outdated version of Electrum, so a few of the commands were different; I right clicked the new address under the "Addresses" tab and clicked "Request Payment", after which is I was taken to the "Receive" tab, with the new address in the "Receiving Address" field, and the correct amount of BTC in the "Requested amount" field, and I pressed "Save".
I now have the request for the correct amount of BTC in the "Requests" list, with "Pending" as the status and a wallet Balance of 0. This deviates heavily from what the online guide I was following had as the result, as the amount of BTC seemed to immediately be available in the Wallet on the guide.
From researching a bit, I'm starting to think that this is because I had already used Electra, and therefore was using a wallet that had a seed, which is apparently a no-no for importing private keys.
What can I do now? Have I messed up the transfer beyond repair, is there something else I need to do, or do I just need to wait a few more hours for the pending transfer to go through? If my explanation is too vague feel free to ask me to clarify whatever I need to, thank you!
