Hello there, @jannyell.
I'd be glad to join the thread and help you change the asterisk to check-mark.
As mentioned by our Established Community Backer, qbteachmt, the asterisk appears on the register when the reconciliation process was not yet completed. To change the asterisk mark to check-mark, you may need to resume the reconciliation process. You have to go back to the Begin Reconciliation window, re-enter the beginning balance and proceed with reconciliation as usual.
To learn more and for the detailed instructions, you may check this article: Reconcile bank and credit card accounts.
Feel free to add a post/comment below if you have any other reconciliation concerns, I'll be always here to help you. Wishing you the best!
