One day I was watching YouTube, and decided to watch Technoblade (RIP, dude...), and I was watching the video where TNT is summoned every 10 seconds (video shown below).
I wanted to recreate that challenge and tried this command:
/summon minecraft:tnt ~ ~ ~
...but it just summons a TNT explosion animation when it blows up. I couldn't find anything else in Minecraft or on the internet. What is the command for summoning an ignited TNT block as of 1.20.4?
