You don't have to have a key to complete a CW contact. Many people use software to send (and sometimes decode) CW; particularly "canned" contest exchanges. I noticed this in my LoTW account Station Call Sign W5ESE DXCC UNITED STATES OF AMERICA (291) CQ Zone 04 ITU Zone 07 Grid EM00 State Texas (TX) County Hays Worked Station Worked I2SVA DXCC ITALY (248) CQ Zone 15 ITU Zone 28 Grid JN45NT Date/Time 2006-02-19 20:58:00 Mode CW (CW) Band 20M Frequency 14.00000 QSL 2011-01-21 21:42:18 Record ID 262541607 Received: 2010-01-30 23:52:23 I noticed the 'QSL' timestamp on my contact is almost identical to the 'Received' timestamp on yours. So that suggests I2SVA submitted a large batch of old logs to LoTW on 2011-01-21. That means probably you submitted a log with the matching contact on 2021-07-10. If you log in to your LoTW account, and go to 'Your Account', then select 'Your Activity', it will show you the dates and times that you submitted signed logs. You will probably find one on 2021-07-10. I you click on the blue highlighted 'Result', it will show the name of the tq8 file you submitted, like this.

My guess is that you tried something in 1999 WPX as a "one-off" experiment, then forgot about it during the subsequent 22 years. I think LoTW is a pretty cool system.
