I need to move some quickly
Then you should not have chosen a Bitcoin Core wallet. Bitcoin Core requires substantial time to fully synchronize with the network if you are starting it up for the first time.
If you were in a hurry, you would have been better off installing a lightweight wallet such as Electrum.
Unfortunately, since you already sent the bitcoins to Bitcoin Core, the easiest thing to do now would be to leave it running and wait for it to finish synchronizing. As achow101 mentioned, you might want to turn on pruning if you don't have enough available disk space.
