Apple Macbook Pro Hard Drive Repair Help Please

Cause of the mistake, i was being dumb and wanted to use my backup timemachine drive for an external drive, so I dragged the timemachine folder out of it and tried to empty the trash can, half way through I realized that it was trying to wipe my whole back up of my computer which would have been forever. So I panic, force shut off the computer, disconnect the drive and restarted the computer. My drive says 200 gb free when I know there is 400 left. So obviously the trash files are still around in my hard drive.
Did a disk verify and there is something wrong and the computer wants me to reboot and use repair upon rebooting the mac. I haven't done this in a while so I'm not sure if it's expecting me to have a backup from time machine.... the one i just fatally "deleted" or if it gets rid of the trashed files. Can someone help me please before I lose A LOT of work.

Update : And let's say I did need a back up, then if I just backed it up right now, with the missing but still taking up space files, would I still get those files in the back up or no?
