Recovery phrase? AFAIK Bitcoin Core only support that in form of master private key. Just to be sure, is it human readable (contains multiple words) or only contains 1 long string?

Its 12 words all readable, so not private keys that are generated (this I do not have)

If you have the recovery phrase (12 words pass phrase by default) then try downloading Electrum and recover your wallet using Already have a seed feature. This will be easier for you.

Ok so I downloaded it and imported BTC address, yet its only read only ( I can see BTC balance). Now I tired new wallet and import seed yet no BTC is within wallet after entering my seed. So I went to see the read only BTC wallet where I can see my balance yet seed is grayed out.

I also attempted import with 2 factor auth that some others users recommended.

I'm a little closer, meaning I can now see my BTC, I am unable to send funds though only view. Any trick to this?
