Now it should be broadcasted to the network unless if your wallet is offline as the image shown below.
If your wallet shows red the same as my image above it means you are not connected. The transaction will only save in local as the image shows below.
Or if your wallet shows "Syncing" like this
The transaction is not yet broadcasted and it should show something unconfirmed transaction in the history tab(it means it's not broadcasted yet to the network/ it's stuck on the local transaction due to syncing/internet issue.)
If that's the case you must fix it first before the transaction can be broadcasted to the network.
