I messed up the partitions in the SSD while removing Linux. Tried to reboot and there was no startup disk, it went to recovery mode. I tried to do cmd + R, cmd + option + R, cmd + shift + option + R to enter recovery and tried to reinstall Mac OS but no progress.
It was running Catalina when this mishap happened.
TIA
MacBook Air 13″, macOS 10.15
Cold Boot and immediately hold these three keys altogether and at the sometime >> Command+ Option + R. This is Internet Recovery Mode. You MUST have internet access for it to work. It is much like the regular recovery mode except it is booting from Apple Servers. It will take much longer to load. Once in recovery mode use Disk Utility and choose the Top Most Device usually called Apple SSD or something like that. Now, Partition that drive as one partition and format as APFS with GUI. This prepares for the next step. Back out of Disk Utility and download the latest version of macOS offered and install.

Did you install Linux from USB drive? If so, use the Linux USB to boot into. The problem is lightly Linux reformatted the drive as ext4 which is unreadable my MacOS or Windows. While in Linux look around for an App called " gpart ". Will have to use that Linux App to re-partition your internal drive and format to something macOS understands like fat32.
Suggest making a Bootable Install disk of Catalina and again, Option boot to Catalina USB. Use the DU ( Disk Utilities ) to re-partition internal drive as APFS and GUI format. Once done, install Catalina
Can you guide me how can I make a bootable USB when I don't have Mac OS installed? Thank you. And after I ran into trouble, I formatted the SSD. Now I only have Linux on my SSD.
Thank you Phillips. I solved it before reading your comment. I kind of used the similar approach. It wasn't working yesterday. I don't know why. Thank you again.
