A few passages that support an age of accountability:
Matt 19
13 Then little children were brought to Him that He might put His hands on them and pray, but the disciples rebuked them. 14 But Jesus said, “Let the little children come to Me, and do not forbid them; for of such is the kingdom of heaven.”
That one speaks for itself. The age could be as high as 20:
Ex 30
14 Everyone who is numbered in the census, from twenty years old and upward, shall give the Lord's offering. 15 The rich shall not give more, and the poor shall not give less, than the half shekel, when you give the Lord's offering to make atonement for your lives.
This next one requires some thought:
Matt 7
13 “Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. 14 Because narrow is the gate and difficult is the way which leads to life, and there are few who find it.
Rom 5
20 Moreover the law entered that the offense might abound. But where sin abounded, grace abounded much more,
The first passage indicates that relatively few will be saved. The second indicates the opposite. This makes sense if there is an age of accountability, and the first passage is referring only to those over the age, which makes sense as they are the ones able to differentiate the paths.
