important '' i am already doing it in recovery''

The warning is normal—if you are booted to that volume no repairs can be made anyway, only checked.

Barney-15E spells it out above and has pointed you in the right direction...

Boot into Internet Recovery (Option Command R) and from the dropdown menu: Utilities>  Disk Utility> run the First Aid on your Macintosh HD (and the "Macintosh HD-Data" volume as well if Catalina/Big Sur) If errors are found and repaired, run again until no errors reported.

Disk Utility>View>Show All Devices The best sequence is —

• Volume level

• Container level

• Parent drive

Recovery: https://support.apple.com/en-us/HT204904

Base system is the Recovery OS. You are checking Recovery, not your Mac's startup volume.

It gives the warning because it is the active OS volume.

What are you trying to check?

You can use the version in Recovery to check and repair your normal startup disk. Checking the recovery system itself is useless; it's not changeable, and for the Internet Recovery one, isn't accessible from your end.
