Flashing question Mark after removing MacBook Air from find my device

Recently I removed my MacBook Air from my devices to turn on find my MacBook. I went to reset everything, to find a flashing folder. I have no idea where to start but I’ve been working on this for 5 hours. HELPP.. when I goto reinstall macOS it pulls up macOS Sierra, when I press continue- agree- it says select the disk where you want to install macOS - then it doesn’t show a disk to choose from.HELPPP

How to reinstall macOS

From the Linked page above and Especially the part about

Follow these guidelines during installation:

If the installer asks to unlock your disk, enter the password you use to log in to your Mac.
If the installer doesn't see your disk, or it says that it can't install on your computer or volume, you might need to erase your disk first.
If the installer offers you the choice between installing on Macintosh HD or Macintosh HD - Data, choose Macintosh HD.
Allow installation to complete without putting your Mac to sleep or closing its lid. Your Mac might restart and show a progress bar several times, and the screen might be empty for minutes at a time.
