The cold wallet was never online.
I specifically did the exchange -> hot -> cold steps to get familiarized with each.

blockstream.info shows:
.Cold wallet 2 tx; .00091904 received and .00091904 spent
.Hot wallet 1 tx; .00090639 received and .00090639 unspent

I think this establishes that I attempted one necessary step and that the coin is correctly in the cold wallet?
Thanks to all if one of you can confirm or correct my conclusion.

I'm stuck trying to complete my first transfer into Electrum cold wallet:

.purchased .91 BTC from cash at exchange
.transferred the BTC out of exchange to Electrum desktop hot wallet address
.confirmed receipt of BTC into hot wallet
.sent BTC to Electrum cold wallet address, signed then broadcasted the transaction. Both transactions are green checkmarked and hot wallet emptied.
   I think I missed the step to Export the transaction?
.opened the Electrum cold wallet on Tails OS flash drive
.initiated Load Transaction, but don't have a file to load, nor know what transaction text to provide
   Can someone tell me from where and what information I can pass to the cold wallet to complete the transfer?
Thanks.
