Hello, Linedancer5678.
Restarting to recovery mode can sometimes be a little tricky as for timing the keystrokes. And it's best to do this with a wired USB keyboard. Borrow one if you have to.
I've found what works best and most consistently for me is to press the power button on the Mac, and then when I hear the startup chime press and hold Command-R until I see the Apple logo and progress bar. At that point you can release the keys and let the Mac finish starting up.
If you have attempted this more than a few times without success, then you may have a situation where the internal drive of your Mac is failing or failed. Try restarting into Internet Recovery mode using Option-Command-R or Shift-Option-Command-R. You will need a solid wi-fi connection or, better, an ethernet cable connection to your router for this.

When you have successfully booted into recovery mode, then use Disk Utility > First Aid to check the integrity of your startup drive. You might have to click View > Show All Devices to enable the selecting of the internal drive device. Run First Aid on any indented volume listed for the startup drive, then on any container of that drive (if available) and then finally the drive device itself.
