Hi RabbitKP.082,
I am Dave, I will help you with this.
If you open the clipboard app (Windows Key + V can you find your typed data listed there?
If you can, then it is very likely you may have malware, possibly a key logger on your PC, because your typed data should not appear on the clipboard, if you did not copy it.
Open Defender or your preferred anti-virus and run a gull offline scan with that.
Then download the free version of Malwarebytes and run a scan with that
Do either of those find malware on your PC?
