I assume that you are sending Monero to a centralized exchange. Because centralized exchanges partially require manual confirmation. Maybe you can see the coins in your wallet, but they haven't sent the coins to the exchange wallet so you can't make the next transaction. You need to be patient until the exchange team confirms it, or you can send a ticket to the team.
Do not send information in the telegram group, because that information will be used by scammers, and they will contact you asking for a fee, while they cannot solve the case. Send a PM to the exchange admin or group admin!
