How to SCP files from a PC to storage in Termux
By design Android won't allow any other app to access Termux's data directory: /data/data/com.termux/files/home. However you can scp directly to SD card after granting WRITE_EXTERNAL_STORAGE permission.

As referenced in Termux wiki:


  It is necessary to grant storage permission for Termux on Android 6 and higher. Use 'Settings>Apps>Termux>Permissions>Storage' and set to true.


Now to copy files to Download directory:

~$ scp &lt;file_name&gt; &lt;phone_IP&gt;:/sdcard/Download/
