Your coldcard is a signing device, it holds your private keys in an airgapped environment. If you pasted your seed phrase into bluewallet, it now has your keys and they are no longer airgapped as the Blue wallet app has now accessed them.

They both have the same receive and change addresses derived from the same seed phrase. You should make sure you are able to spend the coins from Bluewallet, after confirming that, you can reset your coldcard and create a new wallet with it. Use the recieve address from the newly generated wallet and send the coins from blue wallet to tgat address.

Once receievd, uou can copy the json of the new wallet and create watch only wallet with it in Bluewallet.

Be very careful when making sure you can spend he coins in Bluewallet.
