I merged over from Electrum 1 to 2.7 then 2.8(If I recall correctly that was Bitcoin core .01 to .02 then .03) then imported them onto another service. -snip-
These are all Bitcoin exclusive clients while the description in the OP has detail like "
staking" that is unrelated to those Bitcoin clients and the Bitcoin.
What do you mean by "
merged over from Electrum" and then "
that was Bitcoin Core"?
Seems like you're remembering common crypto terms that are appearing over the internet and mixing them with the actual data that you can recall.
Have you recovered to some extent?
I had an accident and am still recovering from a significant amount of brain damage, and have little recollection of a lot of my life, trying to remember passwords is not going to happen..... I cannot remember where exactly I put my cryptocurrency and have 4 or 5 different wallet files to different exchanges -snip-
For starters, try to read this thread and see if you can find something similar from the list:

guts" when it tells you that something is familiar, find actual data.
