How do I make command blocks distinguish between an in ground arrow and in ground tipped arrow?

I know how to make explosive arrow, but I want to have only strong harming arrows explode; the command is:

execute at @e[type=minecraft:arrow,nbt={inGround: 1b}] run summon tnt ~ ~ ~

I have tried to add a "CostumPotionEffect" nbt, but it doesn’t explode the strong harming arrows i take from the creative inventory; how can I fix the command?
