I did a small test amount of BTC back to Coinbase Pro which took 1 hour 15 minutes to arrive, is that amount of time the norm?
Not exactly. It depends on the network congestion and the amount of sats you used for fees when sending from non-custodial wallets. If it's high enough, it could take 10 minutes.
When you sent BTC from Coinbase Pro, the exchange probably set the fees high that it was immediately added on the next block.

Coinbase Pro has given me an address to send ANKR to but it is the Trezor that I am having difficulty with.
In Trezor, MyEthWallet it is only giving me the option to send ETH. Nothing is clickable in order to change that to ETH tokens, ANKR.
ERC-20 token address and ETH are the same AFAIK.
