I can help you make a transfer in QuickBooks Online (QBO), pin.

Beforehand, may I know the specific error message you encountered?

If you've followed this article to record a credit card transfer in QBO and get the error please know that you can’t use multi-currencies to transfer funds from a bank to a credit card account. That may be the reason why you get the error message.
