I'd leave them alone for a week. Then check to see if there are any new queen cells. If one half goes queenless the worst thing to happen is that you have to recombine the two halves again, or find a queen somewhere to put in, or add a frame of young brood. No great problem.
The only thing you did 'wrong' was not verifying that there was young brood in both halves of the split. Not finding the queen is common. As long as there is young brood, no problem.
Now, if you can find the queen that's nice; you can separate her into a nuc or do whatever you want.
